A four-member team returned to China to carry out Operation outrat, while Zhang, Chu Liang, Wang Yu and Xiao Lan returned to China to carry out Operation outrat, with the aim of saving Wang Ziyang. Wang Ziyang was finally found by Zhou Yi, an undercover agent who broke into the enemy's interior, and came out after giving it to him. Wang Ziyang is difficult to save. Finally, in order to save him, the four-person team also sacrificed two people, Zhang and Chu Liang. From the beginning, because of the traitor's betrayal, these four people were in danger, because the enemy opened a tight encirclement for them and wanted to catch everyone. In this grim situation, the four men finally overcame many difficulties and completed the task of rescuing Wang Ziyang. Wang Yu also found her and Zhang's children and reunited with them.
Second, the purpose of saving Wang Ziyang is to expose the crimes of the Japanese. The four-person team came back to rescue Wang Ziyang in order to expose the crimes of the Japanese. In order to better control the people of China, the Japanese developed germ warfare and conducted experiments on human bodies. Wang Ziyang is the object of their experiment. Wang Ziyang ran out from there, so the four-person team wanted to find Wang Ziyang, rescue Wang Ziyang, and let Wang Ziyang, a witness, make the crimes of the Japanese public. The Japanese committed heinous crimes in China, and only those who experienced them personally are the best evidence. Zhang Yimou's Cliff truly reflects the cruelty of the Japanese.
Third, the significance of saving Wang Ziyang, Wang Ziyang, was a survivor of Japanese experiments on human bodies, and there was also Wang Ziyang in history. He led the prisoner who was doing the experiment out of prison. The successful escape of Wang Ziyang is of great significance, which can let us know the truth about the Japanese bacteria test and make the Japanese crimes known to the world. After Wang Ziyang was rescued, he devoted himself to the revolutionary cause, but later he died, so the film Above the Cliff can be said to commemorate the martyr Rainbow Ziyang.
