Following the Hong Kong-Zhuhai-Macao Bridge, the Dalian Bay Cross-sea Traffic Project is another cross-sea traffic project with complex technical conditions, high environmental protection requirements, and extremely high construction requirements and standards in the history of China's transportation construction. The tunnel is 5.1 kilometers long and has a total of It consists of 18 sections of immersed tubes. How does the Dalian Bay Subsea Tunnel solve the technical problems and realize the precise docking of immersed tubes under 30 meters of water? The audience can find the answer in the documentary "China in Progress".

The special program "Endeavoring China" launched by the Central Radio and Television Station Film and Television Documentary Center will be broadcast on CCTV-9 Documentary Channel every day at 12:50 noon from April 30 to May 4. CCTV, CCTV, etc. New media platforms will also be launched simultaneously.
By showing the fiery scenes of China's "new infrastructure", science and technology, environmental protection and other major construction projects, the film comprehensively showcases the high-spirited style of Chinese workers in the new era, and leads the audience to experience China's appearance under the CUHK infrastructure project.

For example, the Baihetan Hydropower Station has a maximum dam height of 289 meters, the third in the world; the total water thrust of the reservoir dam is 16.5 million tons, the second in the world; the seismic parameters of the 300-meter ultra-high arch dam ranks first in the world.
The Baihetan Dam is the first dam in the world where the entire dam section is poured with low-heat cement concrete. During the concrete pouring process of Baihetan Dam, the intelligent construction platform played a key "temperature control" role, making the ideal of a "seamless" dam finally realized.
For example, as the first Universiade supported by 5G, the Chengdu Universiade will be led by the concept of "Smart Universiade", presenting the power of Chengdu's technological innovation to the world. Many competition venues have injected a lot of "black technology" while guaranteeing the "face value".
Each episode of the documentary revolves around the construction process of a major project, covering transportation, construction, energy and other fields. The whole film is in the form of a short documentary with a small volume of 5 minutes per episode.

It is reported that the film innovatively adopts the form of cooperation in the production. The main stations of the main station are responsible for on-site shooting of major domestic nodal engineering projects, and then sent back to the record channel after unified editing, packaging, and centralized launch. While ensuring quality Effectively save production time. In the shooting, the film uses a combination of aerial photography, ground photography, underwater photography and other means to comprehensively and three-dimensionally restore and present the details of large-scale engineering construction, bringing a feast of engineering aesthetics to the audience.
