　　Editor’s Note: The integrated protection and restoration project of landscape forest, field, lake, grass and sand ("landscape project") is a landmark project to practice the concept of life community of landscape forest, field, lake and grass. Since the "Thirteenth Five-Year Plan", 44 "landscape projects" have been deployed and implemented in the important ecological barrier areas of "three districts and four belts". In December, 2022, "China Landscape Project" was selected as one of the first ten flagship projects of world ecological restoration by the United Nations. From now on, this edition will publish a series of reports on "Beautiful China Landscape Project" to show the exploration and achievements of integrated protection and restoration in various places.

　　"Look, there is a rock sheep on the right!" When the vehicle drove into Helan Mountain, Ge Yihong suddenly shouted. Looking up, three gray rock sheep are drinking leisurely by the stream, and in the distance, Helan Mountain is covered with a layer of green.

　　This is Shitanjing Street, Dawukou District, Shizuishan City, Ningxia Hui Autonomous Region, located in the hinterland of Helan Mountain. Ge Yihong, the 60-year-old stationmaster of street sanitation station, lives here all the year round.

　　Helan Mountain is an important natural geographical dividing line and an important ecological barrier in northwest China, which is rich in coal and other resources. Since 1950s, large-scale disorderly mining has seriously damaged the mountain landform. In 2018, the pilot project of ecological protection and restoration of lake grass in the landscape forest field at the eastern foot of Helan Mountain in Ningxia was officially launched; In 2021, the comprehensive improvement of the ecological environment of Helan Mountain was jointly recommended by the Ministry of Natural Resources and the World Conservation Union as one of the 10 typical cases of ecological protection and restoration with China characteristics. Today, Ningxia has completed the comprehensive renovation of 214 points inside and outside Helanshan National Nature Reserve, with an area of over 405,000 mu.

　　Mine management, shut down and quit coal and gravel enterprises.

　　"In the past two years, the effectiveness of governance has gradually emerged. There have been new changes in the former Shikanjing mining area, and many animals that have lived in the mountains for a long time have gone down the mountain." Ge Yigong said, looking out from time to time. "You see, this ‘ Quack chicken ’ How beautiful! " Along the direction of the finger, I saw the stone pheasants with bright fur and round posture strolling in the grass in droves, and in the distance, the golden eagle with wide wingspan was hovering in the sky … …

　　Ge Yihong was born, grew up and worked in the mining area. Different from the days when the mountains were quiet and natural and animals swarmed, the Helan Mountain used to be full of people and the sound of mining rumbled.

　　Since 1950s, Helan Mountain has entered the stage of large-scale industrial mining. Mining enterprises blossom everywhere, and there are countless informal small coal mines. "At that time, it was also called Shikanjing District. At the most brilliant time, it was inhabited by more than 100,000 people. There were hospitals, shopping malls, schools and restaurants, including Helan Mountain ‘ Baili mining area ’ Known as. " Ge Yihong said.

　　However, the large-scale exploitation of mineral resources has seriously damaged the mountain landscape, and some wild animals are on the verge of extinction due to the sharp compression of their habitats. There are about 50 coal enterprises scattered in the Dagugou area of the carboniferous well, including 5 large pits formed by open-pit mining and more than 10 continuous slag hills. Dust all over the sky and sewage cross-flow, which greatly destroyed the natural ecosystem of Helan Mountain.

　　"In the past, there were coal washing plants everywhere. Black wastewater flowed in the ditch and the land was dyed black. Private mines cut off the whole mountain, and dug a large pit for quarrying, forming a gully with a depth of 100 meters. " Ge Yihong still remembers the scene of that year. "Red deer and rock sheep have never been seen. Wearing a shirt, it will be dyed black for a while, and residents are afraid to dry clothes outside. "

　　With the progress of the central environmental protection inspector, in 2017, Ningxia began to vigorously rectify the ecological environment of Helan Mountain. Rujigou, Shitanjing and other mining areas closed all open-pit coal mines, 83 mining rights were all withdrawn, and 561 "scattered pollution" enterprises in the centralized coal processing zone at the foot of the mountain were also shut down and banned.

　　After clearing the mine, cutting the slope and lowering the platform, a vigorous mine management began. "Following the Helan Mountain Clean-up and Renovation Command, everyone rushed to the slag platform piled up by abandoned coal gangue and transported it day and night." As the stationmaster of Shitanjing Street Sanitation Station, Ge Yihong participated in the whole process.

　　Coal gangue was piled up into a waste platform with a height of nearly 100 meters by a mine car, and then cut into a "terraced field" in order to reduce the slope and prevent soil erosion. Subsequently, the mountain-high unclaimed slag pile was covered with loess nearly 50 cm thick, which gave the black slag mountain with a layer of "skin" that could retain green vitality. At the same time, "follow the mountain, follow the mountain, follow the mountain", restore the topography according to the shape, and reduce the safety hazards such as landslides and mudslides.

　　During the treatment period, the resident population of Shitanjing decreased sharply, and Ge Yihong moved from the hinterland of Helan Mountain to Dawukou District at the foot of the mountain with the coal miners. Nowadays, standing at the top of the Dagugou governance area, new "mountains" have sprung up. "This is smoothing what was left behind ‘ Scar ’ Only by curing the mine can there be room for further greening. " Ge Yihong said.

　　Planting trees, building greening projects and implementing ecological restoration.

　　On both sides of the 302 provincial highway crossing Helan Mountain, drip irrigation pipes tightly wrap the towering slag platform like fishing nets. "This is to ensure the survival rate of seedlings. From spring to winter, water should be poured at least 10 times." Ge Yihong said. It was spring, and I saw that many bare land had been covered by all kinds of newly planted saplings.

　　After the retreat and restoration of Helan Mountain mine, how to effectively plant trees and increase green has become the number one problem in Helan Mountain management.

　　To plant trees, we should start with selecting suitable tree species. Since 2018, Shizuishan Ecological Protection Forest Farm has conducted a series of experiments in Helan Mountain through cooperation with Ningxia University and other scientific research institutes, and finally determined Caragana korshinskii, Salix psammophila, Elm, Pinus sylvestris var. mongolica and Robinia pseudoacacia as the main tree species. "Helan Mountain is a stone mountain with thin soil layer and difficult vegetation growth. Moreover, the annual rainfall here is only two or three hundred millimeters, but the evaporation is more than 10 times. Native plants that are cold-resistant, drought-resistant and salt-tolerant are the best choice. " Zhang Tingxie, director of Shizuishan Ecological Protection Forest Farm, said: "‘ Seabuckthorn, Caragana korshinskii and Prunus armeniaca on the top of the mountain wear hats, and two apricots are wrapped around the waist on the hillside ’ This is what we have summed up. "

　　Although he has moved out of the mining area, he heard that there is a green restoration project. Ge Yihong returned to Shihanjing, joined the army of tree planting, and got busy in the Dagugou area with the heaviest restoration task.

　　Waving steel drill and shovel, struggling to dig hard sand and gravel ground, digging out 80 cm square tree pits, and then righting, ridging, tamping and watering the seedlings. "Dig up the thin soil layer, and here is the coal gangue that can’t store water. If you want trees to survive, you have to cover them with moisture-retaining soil, nutrient soil and sealing soil, step on them layer by layer, and finally mention them slightly to make the roots of seedlings grow in the same direction. " This is known as the "three steps and one mention" trick, and Ge Yihong and the tree planters are well known. "Now, the survival rate of trees can reach 85%." Ge Yihong said.

　　Planting trees in spring and autumn, watering in summer, controlling pests and diseases, and conducting fire inspections in winter, Ge Yihong "soaks" in Helan Mountain all year round. Nowadays, driving around the mountain along the ecological restoration area of Helan Mountain, you can see "green-planting people" digging holes to change soil, placing saplings and lifting water to irrigate … … "The apricot at the foot of the mountain was planted by us a few years ago. When the apricot blossoms are in full bloom, they are layered. This year, we intend to put this cinder mountain in green. " Zhang Tingxie said.

　　Systematic improvement of governance results, integrated development of ecological culture and tourism.

　　"Now there are less than 100 people left in Shitanjing Street. After the restoration of Helan Mountain is completed, my life will be idle." Ge Yihong, who returned to the Shitanjing, did not go down the mountain and stayed in the old mining area. However, it was not long before the days of "long years in the mountains", the Shitanjing became lively again.

　　Since autumn and winter of 2021, Shizuishan City has mobilized 105 units, including party and government organs, enterprises and institutions, and units stationed in stone areas, to carry out greening activities in eight mine ecological environment management areas in Dalanggou District, Shitanjing Street, Helan Mountain along the 302 provincial highway. At present, it is the planting period, and many staff members are busy setting out, waving picks and shovels, and leveling the ground.

　　"Through ‘ Green Planting in Pieces in Helan Mountain ’ Activities can plant 12,000 mu of trees a year. " Jia Zengjun, director of the Natural Resources Bureau of Shizuishan City, said: "More importantly, the task of slicing and planting has stimulated everyone’s enthusiasm and made everyone feel that the results of Helan Mountain governance are hard-won. Now the afforestation task is about to be completed. From the closure and rectification of the mining area to the ecological restoration of internal and external integration, and then to the improvement of the governance results system, Helan Mountain is being dressed in green. "

　　Ecological improvement has made Helan Mountain, which once sold coal, have the possibility of diversified development.

　　At 7: 35 every morning, the 7524 train leaves Yinchuan for Rujigou. This small train is called "Shitanjing Tourist", which connects in series with the former coal mining areas such as Dagugou, Baijigou and Rujigou. A 3-hour and 52-minute drive takes passengers deep into the hinterland of Helan Mountain to visit the passionate industrial years.

　　"Eco-tourism+industrial film and television shooting base" is a new way explored in Shitanjing mining area. Since 2017, some old houses in Shitanjing have been repaired and old streets and alleys have been protected. After the establishment of the Shitanjing Industrial Tourism Town Exhibition Hall, Ge Yihong was hired as a commentator to receive visitors: "I didn’t expect the industrial relics left in the old mining area to become a unique advantage in developing tourism. In the past few days, I have received thousands of tourists, and many movies have come here to take pictures!"

　　After several years of management, the ecological function of Helan Mountain has been steadily improved, and the goals of ecological corridor restoration and biodiversity improvement are gradually being implemented. This towering mountain range is witnessing the ecological vision of "green water and green mountains" becoming a beautiful life within reach.

　　At the closing ceremony of the 2008 Olympic Games, 18 districts and counties in Beijing will set off fireworks together to record this historic moment, so that gorgeous Beijing and happy Beijing will go down in history forever. The fireworks feast at the closing ceremony and the Bird’s Nest will surely become the focus of world attention. To this end, Xinhuanet specially invited Zhao Weiping, the general commander of the Bird’s Nest fireworks display, to introduce the related situation of the Bird’s Nest fireworks display at the closing ceremony.

Zhao Weiping, the general commander of the 2008 Olympic Games Bird’s Nest fireworks display, was interviewed by this reporter.

　　Zhao Weiping: Everything is ready for the fireworks display at the closing ceremony.

　　Moderator: The expected closing ceremony is about to be staged. Apart from the rich programs prepared by ourselves and the 8-minute performance in London, the fireworks will bring the atmosphere of the audience to a climax. What is the preparation for the fireworks in the closing ceremony?　

　　Zhao Weiping: We have basically finished the preparations for the closing ceremony. There are 420 launching sites and 8,138 fireworks in the closing ceremony. It is necessary to rearrange the layout and rearrange the launcher. At present, the preparations include the installation of fireworks, the structural installation and wiring of the shelves. The rest of the time we will do some tests on them and check them a few more times to be foolproof.　

　　Moderator: Will some equipment at the opening ceremony continue to be used at the closing ceremony?

　　Zhao Weiping: The equipment that is exactly the same as the opening ceremony is gone. They have all been readjusted. Because each launcher actually involves different specifications and quantities, basically nothing used in the opening ceremony can be used in the closing ceremony. We hung many launchers again and rearranged them, because after all, the products are still very different. This is the difference between the opening ceremony and the closing ceremony.

　　Moderator: The Bird’s Nest has been in the competition all the time, and the performance place of the closing ceremony is also in the Bird’s Nest, which is bound to bring some difficulties to the preparation of fireworks. What difficulties have you encountered? How do we overcome it?

　　Zhao Weiping: The biggest problem encountered in the construction of the closing ceremony is that the construction is not allowed during the day, and the other is that it rained heavily two nights ago, which brought us some difficulties and increased the intensity of our work. Our team basically worked all night every day. In addition, there is no light on the bird’s nest at night, and we mainly rely on the peripheral auxiliary lights to illuminate the work, which also increases the difficulty of our work. But even under such circumstances, everyone made unremitting efforts, especially the encouragement brought by the success of the Olympic opening ceremony. It should be said that the whole team is United as one and has high morale, hoping to complete the closing ceremony successfully.

　　Moderator: Our staff is still in a very good state, without any slack?

　　Zhao Weiping: No. We also held a mobilization meeting yesterday, which was the last mobilization before the closing ceremony. I hope everyone can make a great effort to make the closing ceremony beautiful. After these mobilizations, everyone is still very active. Everyone performed very well, and I was very touched. I think it must be the fighting spirit of the Olympic Games that encouraged everyone. I am very satisfied with the performance of the team, as a person, as the leader of the enterprise or as the commander-in-chief of the fireworks display team.

　　Moderator: This time, the preparation is quite adequate, but the closing ceremony has not been rehearsed. Will you feel a little insecure?

　　Zhao Weiping: No, because as the closing ceremony itself, there is no substantive rehearsal, but every discharge in front of the Bird’s Nest can be said to be a rehearsal for the closing ceremony. Because each discharge and installation will bring more experience, more protection and more confidence to the next one.

The staff installed the Bird’s Nest fireworks in the daytime and at night (picture provided by Panda Fireworks Company).

　　The fireworks of "Xiangyun", the first appearance of the closing ceremony, will ignite the night of passion.

　　Moderator: Then can you tell us specifically what kind of fireworks will be displayed at the closing ceremony?

　　Zhao Weiping: There are still some differences between the closing ceremony and the opening ceremony. Everyone has seen the opening ceremony. There are five rings, footprints, some beautiful wings on the top of the bird’s nest, doves of peace, countdown in the stadium, waterfalls, lightning, thunder, including the peony flowers we talked about, and dynamic five-color rings, all of which have their own characteristics. We also used the chip bomb (which is the most advanced in the world at present) and used air launch for the first time. These are the results of our technological innovation.

　　Our main product innovation at the closing ceremony is an auspicious cloud. As we all know, Xiangyun has spread all over the world, and we also hope that the creativity of fireworks can be expressed by Xiangyun, which may be different from our Xiangyun torch. There will be spiral and dynamic fireworks at dozens of points on the top of the bird’s nest, which has never been seen before. Xiangyun has two colors, including a gold one. This is a relatively good product, and it took us about half a year to develop it after receiving the task book from the Olympic Organizing Committee.

　　Another highlight of the closing ceremony is that we have a colorful circle on the top of the Bird’s Nest. After typing, you will see a fireworks circle, which is quite beautiful, and it has been launched twice. We didn’t have such a variety in the last opening ceremony. It exploded in the sky after you hit it from below and saw the effect. The products we used at the opening ceremony last time did not explode in the sky, but this time there will be an explosion in the air, which will present a very beautiful scene and bright colors. At last, a round pattern made by a big fireworks will be formed on the periphery of the bowl at the top of the Bird’s Nest. I think this round pattern also indicates the complete success of the whole Olympic Games, which can also be said to be "round and full". Everyone is happy and safe. The Olympic Games shows her moral through these fireworks, so I think these will also bring you some aesthetic feeling and some new visual impact. The other difference between the closing ceremony and the opening ceremony is that we have more dynamic things running fast on the top of the bird’s nest in the closing ceremony.

　　Moderator: So what is the scale of the fireworks display at the closing ceremony?

　　Zhao Weiping: From the top of the Bird’s Nest, the whole scale of fireworks in the closing ceremony is smaller than that in the opening ceremony. This time, we don’t have bowl products, which means that there is nothing inside the Bird’s Nest, and the part outside the Bird’s Nest is basically the same as that in the opening ceremony.

　　Closing Ceremony The Beijing Municipal Government and the Olympic Organizing Committee hope that the whole city will have an opportunity to celebrate together and hold fireworks celebrations in 18 districts and counties in Beijing, because after all, it was almost seven years since we won the right to host the Olympic Games in 2001, and many people all over the country worked hard for it. On the whole, this scale is unprecedented in Beijing’s history, and it can be said that there is no such scale in the world. At that time, after the closing ceremony, fireworks will be lit in 18 districts and counties at the same time. I think this can be applied for Guinness Book of Records, which has never been seen in any city or at any time in the past.

　　The fireworks display at the closing ceremony is not affected by rain.

　　Moderator: If it rains on the closing day, will it affect the fireworks display?

　　Zhao Weiping: This is no problem. Because we have already installed the fireworks, it can be said that the problem of rain has been solved at this stage, and it will not be affected whether it rains or other circumstances. If it rains heavily, of course we will listen to the organizing Committee, but as far as I know, it won’t rain before the 24th.

　　Entrusted the owner of the lottery shop to buy lottery tickets on his behalf, but he won 14 million prizes. But when I wanted to get the lottery ticket, I found that the boss couldn’t contact me, and even the lottery shop was closed. Upon further inquiry, the winning lottery ticket went to the boss’s friend.

　　The boss took the lottery and ran away? Or do you want to swallow the grand prize? Who finally won the 14 million prize?

　　Yesterday, a reporter from qianjiang evening news came to this small lottery shop in Shengzhou. On November 10th, five days after closing, the lottery shop reopened. After this big prize storm, Xiao Xu, the post-90 s boss, was a little tired. He said, "If the sports lottery shop stops, I may never know for a lifetime, but I am willing to stand up and deal with this crisis."

　　Won more than 14 million yuan.

　　I can’t get the lottery ticket.

　　Things should start from November 5.

　　Mr. Sun, an old lottery player in Shengzhou, followed a group of lottery tickets for a long time, spending 218 yuan a week to follow 109 lottery tickets. Sometimes he doesn’t have time, he will entrust a nearby sports lottery station to buy it. On November 5, Mr. Sun WeChat entrusted Xiao Xu to buy tickets. Xiao Xu is 23 years old. He has just opened this sports lottery station for two months.

　　On the night of the Super Lotto, two of the lottery numbers purchased by Mr. Sun won the first prize, and the bonus for each note was 7114758 yuan. In this way, Mr. Sun won more than 14 million yuan.

　　Mr. Sun was so excited that he called Xiao Xu immediately. Xiao Xu also confirmed that Mr. Sun won the lottery. Who knows that after this call, Xiao Xu can’t contact and the store is closed.

　　Seeing that the prize is about to be redeemed, but the lottery ticket is not available, Mr. Sun is anxious.

　　There is only one lottery ticket.

　　There are two winners.

　　The lottery ticket that won the grand prize is in the hand of Mr. Ying, a friend of Xiao Xu. What’s going on?

　　The following is Xiao Xu’s self-report:

　　On the morning of November 3rd, Mr. Ying came to my shop. He only bought scratch music before, and this time he asked me how to buy the lotto. I recommend him to buy a set of numbers that Mr. Sun often calls. In the evening, we watched TV together. On November 4th, at about two o’clock in the morning, he gave me 220 yuan to buy lottery tickets. But the lottery machine was off at that time, so I told him to help him type out the lottery ticket the next day. Unfortunately, I forgot later.

　　On November 5, I asked Mr. Sun on WeChat as before if he wanted to type out the lottery ticket he had been following. Mr. Sun said yes, so I typed the ticket for him.

　　After the lottery that night, Mr. Sun called me, and I was very excited. But this time I remembered that I only had one set of lottery tickets.

　　I’m a little flustered, because it’s more than 10 million yuan after all, and we ordinary people can’t earn so much money in our lifetime.

　　Who will win the lottery? Mr. Ying told Xiao Xu that he had called and paid the money on the spot, so the lottery ticket belonged to him. So, Xiao Xu handed the lottery ticket to Mr. Ying that night.

　　Who should the lottery go to?

　　Shopkeepers, they asked seven lawyers.

　　Xiao Xu said that he later found that there were more than 20 people around the door of the store, and he panicked, so he turned off his mobile phone and the store was closed.

　　Here, Mr. Sun, who was in a hurry to get angry, consulted a lawyer, and the lawyer suggested applying to the court for property preservation.

　　On November 7, when Mr. Ying took the lottery ticket to win the prize, he found that it had been frozen.

　　For the ownership of the grand prize, the two began to negotiate.

　　Xiao Xu also clarified to us that he has been negotiating with two lottery buyers and has not run away. "When people see me close the door, they must think I’m looking for ‘ Tuo ’ Stealing the grand prize, or I ran away with the lottery ticket. In fact, the next day, I contacted Mr. Sun with my mother’s number and told the story, which was evidenced by the call record. "

　　Xiao Xu said that for this matter, he and Mr. Ying consulted different lawyers seven times. "Shengzhou consulted four and Hangzhou asked three."

　　Xiao Xu is concerned about whether he is responsible for this matter. What Mr. Ying asked is whether he can win the grand prize.

　　Lawyer: Let’s see whose evidence is reliable.

　　Who should win the grand prize? Let’s listen to the lawyer.

　　Lawyer Chen Yilai of Zhejiang Times Commercial Law Firm analyzed: Mr. Sun entrusted Xiao Xu to buy lottery tickets through WeChat, and the entrustment relationship was still established whether he paid or not. If Mr. Sun can’t get the lottery ticket, he can file a lawsuit, and the WeChat message between him and Xiao Xu can be used as electronic evidence.

　　What about Mr. Ying? According to Xiao Xu, Mr. Ying paid in cash at that time, accompanied by Mr. Ying’s wife and a friend, and there was no other physical evidence. The lawyer explained that the key evidence identification mainly lies in documentary evidence, and witness testimony has only an auxiliary role, while the effectiveness of interested witness testimony needs to be verified.

　　If Mr. Ying wants to get back the lottery prize, he can sue Xiao Xu and ask the other party to compensate according to the amount of the winning lottery ticket. This is a typical contract breach lawsuit. But effective and sufficient evidence must be provided.

　　Outcome: Who will get 14 million yuan?

　　On November 9th, the lawyers of Mr. Ying and Mr. Sun negotiated, and the lottery ticket went to Mr. Sun. After that, the lottery ticket was successfully redeemed and the sports lottery station reopened on the same day.

　　Mr. Ying, who passed the grand prize, said that his mood these days is like riding a roller coaster, going back and forth from the peak to the bottom countless times. However, he and Xiao Xu have been friends for many years. If they cut off contact for lottery tickets, it would not be worth the loss, so they have no intention to sue Xiao Xu.

　　China News Service, August 8 th: The Secret of the "Bird’s Nest" Fireworks (I): Look at how the peony blooms.

　　China News Service reporter Wu Qingcai

　　At the opening ceremony of the Beijing Olympic Games tonight, red peonies are in full bloom over the "Bird’s Nest", and there are many strange shapes such as the Olympic rings and the dove of peace. So, how on earth are the peonies blooming over the Bird’s Nest?

　　Zhao Weiping, the commander-in-chief of the "Bird’s Nest" and the Great Wall fireworks display team at the opening and closing ceremonies of the Beijing Olympic Games, revealed to our reporter the secrets of the seven classic shapes of fireworks that night.

　　The First Classic Modeling-How Peony Blooms

　　The first climax of the "Bird’s Nest" is to interpret the whole process of peony, the national flower, from budding to blooming, and suddenly the Bird’s Nest turns into a red ocean of peony. From the blossoming of flowers and bones to the "relay" opening of petals, and then to the blooming of peony, the blooming process of "peony blossom" took only eleven seconds, but the number of fireworks was 4,845.

　　Zhao Weiping, chairman of the national brand Panda Fireworks Company, said that in order to make the whole red peony cover the whole bird’s nest, the "Peony Blossom" was set off all the steel frames at the top of the bird’s nest and the upper edge of the bowl of the bird’s nest. In order to choose the right color and fully show the elegance and wealth of peony, the designers of Panda Fireworks screened dozens of schemes and finally chose a peach red.

　　Using the three-dimensional special effects of the computer, the designer drew a huge peony covering the roof of the "Bird’s Nest", and then selected 85 points on the roof of the "Bird’s Nest", each of which was responsible for emitting three petals, each of which was composed of 29 fireworks, symbolizing the 29th Olympic Games.

　　"Eighty-five points have different inclination angles, so as to draw a peony flower that is natural." Zhao Weiping said that when setting off, the "flower heart" was emitted from the inside to the outside, and then the innermost "petal" was emitted, which in turn went over to the outermost petal. When the last petal was opened, 85 points were started at the same time, and fireworks were fired in unison, forming a big peony with bright red and unrestrained enthusiasm.

　　The Second Classic Modeling ―― Turning out the "Olympic Five Rings"

　　That night, five circles of five colors, red, yellow, green, black and basket, appeared in the sky, and the five circles were connected with each other, showing the Olympic rings pattern.

　　"Playing the Olympic rings pattern, some Olympic host cities also had this idea, but it didn’t work out." Zhao Weiping told reporters: The biggest difficulty in displaying the Olympic rings and other patterns with fireworks is that the initiation point and time interval of fireworks are difficult to control. The interval error of each fireworks is less than 0.03 seconds, and the audience can see the circle and the five rings only when they are fired in series at a constant speed. Finally, under the guarantee of new scientific research technologies such as air launch and chip fireworks, the global problem of depicting the Olympic rings with fireworks was completely solved by China fireworks people.

　　The Third Classic Modeling ―― "Silver Waterfall" Flows into the Stand

　　During the opening ceremony, there was a "silver waterfall" nearly 40 meters long, like the Milky Way, which slowly hung down along the bowl of the "Bird’s Nest" and flowed into the stadium. The "Bird’s Nest" stand immediately turned into a silver hall. Fireworks exploded around, but the audience couldn’t smell a trace of sulfur, and there was no worry about sparks.

　　Zhao Weiping said that the diameter of the bowl of the "Bird’s Nest" is about 500 meters, which is more than 40 meters above the ground. This shape requires that the diameter of the "Silver Waterfall" should not be less than 500 meters and the length should not be less than 30 meters, otherwise, the audience will not be able to be there. In order to realize this idea, Panda Fireworks Man has broken through four major problems: environmental protection, safety, tasteless, discharge, quick installation and quick disassembly.

　　The Fourth Classic Modeling ―― "Dove of Peace" Bird’s Nest "Spreading Wings"

　　Careful viewers will find that a pair of snow-white wings were born on both sides of the "Bird’s Nest", flapping up and down, just like a dove spreading its wings and flying.

　　Zhao Weiping told reporters that it is not difficult for the "Bird’s Nest" to give birth to "wings". What is difficult is that the wings should be flapped up and down, showing a dove of peace spreading its wings and flying dynamically. In order to make this dove of peace "smart", the researchers first improved the discharge effect of the traditional fireworks element "white tail", which has only white light and no track left by the tail passing through the air, just like the wings of the dove of peace. In order to make the wings move, the researchers calculated the flapping frequency of the flying dove of peace, so that the "Bird’s Nest dove of peace" fluttered its wings once a second on average.

　　The Fifth Classic Modeling ―― Dynamic World of "Red Flash Bird’s Nest"

　　Its modeling features are as follows: a red silk thread runs through the "Bird’s Nest" as red neon lights keep flashing, and under its embellishment, the whole "Bird’s Nest"

　　"In the flashing, running, jumping.

　　Zhao Weiping said that the first difficulty of the "Red Flash Bird’s Nest" lies in the layout. In order to cover the entire "Bird’s Nest", a launching point should be set up every five meters on each main beam; At the junction of the two main beams, a launching point is also set up every five meters, and all launching points are evenly distributed, so that the whole "Bird’s Nest" can jump in the red ocean; The second difficulty lies in the time difference control, and the fireworks at each point must be lit and extinguished at the same time.

　　The Sixth Classic Modeling ―― "Opening the Tianmen"

　　Its modeling features are: a resplendent arched gate, which appears over the "Bird’s Nest". From closing the door and opening a crack to opening half and three quarters until the Golden Gate finally opens.

　　Zhao Weiping said, "Opening the Tianmen Gate" is difficult to measure in the distance and angle between the ground and air. The distance between the first group of emission points and the angle with the horizontal plane must ensure that the emitted fireworks meet in the air and hand over an arch shape; The distance and horizontal angle between the second group of fireworks must ensure that when the fireworks meet in the air, there is just a gap, just like the door has just opened a gap, and so on, until the Golden Gate opens, the angle is a little off, so the process of opening the door cannot be vividly reproduced.　　

　　The Seventh Classic Modeling-"Countdown" Entering "Olympic Time and Space"

　　9, 8, 7 … At the opening ceremony of the Olympic Games, the first thing that appeared in the air was flashing numbers, which sent a strong signal in fireworks language: the Olympic Games is near! Zhao Weiping introduced that the number nine drawn with fireworks stays in the air for no less than one second. As soon as the number nine goes out, it lights up at eight and flashes again for one second. "If any number stays even in the blink of an eye, the fireworks will not draw a countdown stopwatch, which is synchronized with the stopwatch and does not allow any error.".
