China, a large-scale inspirational challenge program jointly produced by CCTV Comprehensive Channel and CCTV Creative Media, is broadcast on CCTV- 1 at 8 pm every Sunday. On the afternoon of New Year's Eve, nearly five hours of Spring Festival special programs received rave reviews, and six program keywords were successively listed on the hot search list. In the fourth stage, the excitement continues to escalate. Three elementary school students' pk eight-character jump rope hit the Guinness World Record, two masters with quick memory revealed the unforgettable mystery, and more than 2,000 officers and men of the pontoon bridge brigade practiced in actual combat, crossing the 1 100 meter pontoon bridge within 26 minutes in a simulated war environment, which attracted the audience to tears.

Speaking of the Army pontoon brigade in the Eastern Theater, you may not be familiar with it. As an army that has been fighting in the Yangtze River all the year round, they shoulder the dual mission of building bridges in wartime and rescuing and providing disaster relief in peacetime. As a "national professional emergency force for flood fighting and emergency rescue", it has been dispatched many times. Once a disaster occurs, the pontoon troops will charge in the front line, open the road on each mountain and bridge the bridge in case of water. Ensure the smooth transportation of relief materials and the safety of people's lives and property. This time, what they want to simulate is a practical drill, and at the same time, they are completing an impossible challenge: within 26 minutes, they will erect a steel pontoon bridge on the Yangtze River, which is 1 100 meters wide. In order to be close to the actual situation, the scene will also simulate artillery coverage and smoke, which will double test the operational skills and psychological quality of officers and men.
