“The answer is, there are.”

"In recent years, more and more large-scale domestic engineering equipment have emerged in the world, including the world's first thousand-ton bridge rig, namely the Kunlun bridge rig, made in my country."

"This bridge builder not only can pass through the tunnel without disassembly and assembly, but also can withstand strong winds of level 7. This is the only one in the world, and its technical content is ahead of all other countries."

"After the birth of this bridge-making machine, it immediately participated in many key engineering projects in China and played an important role in it."

"The Kunlun not only undertakes the construction of many high-speed rail lines, but even the Fuzhou-Xiamen High-speed Railway, the longest cross-sea high-speed rail overpass in the domestic sea bridge section, was finally completed with the help of the Kunlun."

"In addition, our army has also established a special force - the boat bridge unit. The highest record of this unit is to build a bridge across the river hundreds of meters in 35 minutes, and it can be passed by tanks, armored vehicles and other heavy equipment."

"Now, we no longer have to cross the river with the crumbling iron chain."

In the host's introduction, the scene of the Zhouqiao troops flashed, and then the camera switched, and the host was wearing a cold-proof suit and stood on the top of a mountain.

"Sighters, we are now located on Jiajin Mountain, and our car is parked on the road below. It seems that the cold climate has not affected this battery."

"You can see that since I got off the bus, it was already very difficult to just stand here and talk. I recall what a feat it was for our Red Army soldiers to hike over this snow-capped mountain under extremely harsh climate and traffic conditions."

"Jiajinshan is called "Shenxian Mountain" by the local people. When our Red Army team arrived, the people once said that only gods can climb over Jiajin Mountain."

"This is an incredible mountain. According to legend, even birds cannot fly over, and people should stay away from it, but the fearless Red Army insists on fighting fate."

"As we climbed over the snow, countless heroic deeds emerged in our team, and countless people were buried under this snow forever."

"The most familiar example of everyone is probably the "Monument" we once learned in our primary school texts."

"A military chief who does not give himself cotton coats, a heroic soldier who calmly lights a dry tobacco at the last moment of his life. His image is like all other soldiers who buried their bones and this, and will build a monument in our hearts."

"Even, on the National Highway 351, where we are now on, there may be the heroic souls of the soldiers."

"When it comes to Highway 351, it is the only passage to cross Jiajinshan. Among them, the Jiajinshan Pass section is more than 4,100 meters above sea level. Every winter, due to ice and snow, there will be traffic control for up to three months. During this period, only small cars can pass, which greatly restricts the local economic development."

"However, this situation is about to change, because on December 26 last year, the construction of the Jiajinshan Tunnel officially started."

"According to the design standards, the tunnel is 9.35 kilometers long, the construction period is 4 years, the designed speed is 60 kilometers per hour, and it can be opened to traffic all year round."

"Jiajin Mountain, Jiajin Mountain, birds cannot fly, and mortals cannot reach it. If you want to cross Jiajin Mountain, unless the gods come to the earth!"

"This folk song that has been passed down from the Long March period to this day will be about to be broken soon!"

"The most critical element to break it is our large domestic shield machine."

"In 2002, the shield machine project was included in the national key project. We started with poverty and hard work. In just 6 years, the first composite soil pressure balance shield machine with independent intellectual property rights was born."

"The core technology blockade was broken. For more than ten years since then, we, as latecomers, have continued to break the world's shield field records."

"In July last year, the Jinghua, the largest diameter shield machine developed by my country so far, began to expand its territory. This shield machine has a diameter of more than 5 floors, is equivalent to 7 subway cars, weighs up to 4,300 tons, and is composed of 100,000 precision components. It is known as the king of engineering machinery. It is like a steel pangolin, which can drill tunnels in the mountains, under the water and underground in the city. In the future, it will also be used in the Jiajinshan Tunnel Project."

The picture flashed through a series of shocking pictures of the Jinghua shield machine, and then the camera jumped again.

This time, the host appeared on a vast grassland.

"Friends of the audience, we are now in Songpan Wetland, which is the grassland that the Red Army walked through the grassland during the Long March."

"From 1934 to 1935, the First, Second and Fourth Front Army of the Workers and Peasants' Red Army passed through grasslands, namely Songpan Wetlands, and the areas they passed include today's Songpan County, Hongyuan County, and Ruoergai County."

"Songpan grassland is located in the northwestern Sichuan grassland at the connecting section of the plateau and basin. It has a length of more than 300 kilometers, with an area of ​​about 15,200 square kilometers and an altitude of more than 3,500 meters. Due to poor drainage, large swamps are formed. The aquatic grass is mixed and formed into meadows, covering the swamps."

"The grassland climate is extremely harsh, with an average annual temperature below zero, and rain, snow and storms come and go."

"In such a harsh environment, the Red Army faced three main difficulties, one was afraid of quagmire, two was afraid of rain, and three was afraid of crossing the river."

"Any one of these three will greatly increase the difficulty of the marching process, and what the soldiers faced at that time often had the three at the same time."

"In addition, our soldiers were facing a serious food shortage during the process of passing through the grass."

"Wild vegetables, grass, belts on their bodies, even leather bods on straw sandals, and drum skins on gongs and drums have become the food they rely on for their survival."

"The story that happened in the golden fish hook happened on this grass."

"Based on our interview with old Red Army soldiers many years ago, he once showed us the special skills of "three-eating belts."

"Eat it while cooking, eat it while roasting, cook it first and then roast it."

"This may sound a bit funny, and even when we interviewed, the old warriors expressed themselves with the spirit of revolutionary optimism, but we all know how extremely bad conditions were to give birth to such a sad skill."

"In this team, even the supreme leader cannot escape the fate of starvation."

"Before his death, the Red Army soldier Dai Tianfu entrusted a health officer to bring a paper bag to the leader, which contained a small piece of horse meat sent to the seriously ill. He said that he had nothing to worry about and only hoped for the success of the revolution."

"Now, our revolution has achieved certain success, but at the same time, there is still a long way to go."

"However, at least from now on, Songpan grassland is no longer the same grassland as 80 years ago."

"There are about 130,000 hectares of primeval forest in Songpan County. This forest is now a paradise for rare animals such as giant pandas, golden monkeys, antelopes, and sika deer. The towering mountains contain rich mineral resources, especially the famous Zhangla gold, which is famous for its high purity and high taste. Nearly 100 kinds of precious Chinese medicinal materials such as pine shells and ten-day hemp are growing all over the mountains."

"We have retained the most original and purest appearance of this area. Compared with those who are ulterior motives who talk about environmental protection internationally, isn't this more meaningful?"

The picture kept flashing through the beautiful scenery of Songpan grassland, and the camera switched again amid the amazement of everyone.

"Friends of the audience, now we have finally arrived at the last stop of this 25,000-mile itinerary, which is the holy land of Yan'an."

"Here, we led and commanded the two major wars since then, achieved the first historic leap in the combination of Marxism-Leninism with our country's reality, gave birth to the idea of ​​leadership, and laid the foundation for the republic. The Yan'an spirit nurtured by Yan'an is the great spiritual driving force for our country's revolution and construction."
