The film Watergate Bridge of Changjin Lake is a sequel to the Battle of Changjin Lake. Their backgrounds are roughly the same, but as a sequel, the film Watergate Bridge in Changjin Lake will go deeper. The main background material is that at the beginning of the founding of New China, the US military launched the Korean War to suppress China. Because North Korea is on the border with China, the China administration has to support North Korea. If we sit idly by, there will be very bad consequences in the future, just like a sentence in the play.

This film is taken from the historical segment of the War to Resist US Aggression and Aid Korea. Because the new China was just established at that time, and the foundation in all aspects was not stable, the US military wanted to start from the border of China, with ulterior motives, and wanted to destroy our newly established new China and invade our new China bit by bit. At that time, President Mao Zedong made a very correct decision. The War to Resist US Aggression and Aid Korea not only helped New China to consolidate its position in the world and strengthen the building of friendly relations, but also promoted the development of China and created a bright future.

It is precisely because of the War to Resist U.S. Aggression and Aid Korea that a peaceful and safe social environment has emerged. In the play, we can deeply understand that the new China has just experienced War of Resistance against Japanese Aggression, and the people don't want to wage war again, but they want to live a peaceful life, but this battle is still to be fought for the sake of the younger generation and the future development of new China. During the War to Resist U.S. Aggression and Aid Korea, we saw that all the soldiers in China experienced great setbacks, the natural environment was harsh, and their equipment was inferior to that of foreign enemies. China's soldiers were full of blood and firm in heart, which became the most important reason for the final victory of the War to Resist US Aggression and Aid Korea.

It is precisely because of the bloody battles of our ancestors that we have peace and stability now. They sacrificed themselves and created good conditions for us. We should keep in mind history and mission, follow their example and work hard to realize the great Chinese dream of the Chinese nation.
