The story took place in the 1930s. The master selling Laiyang pears and Ye Zhiqiu, who likes singing opera, are childhood friends. The master wants to travel to Shanghai, and he wants to study opera in Beiping in autumn. The master promised to pick her up in Beiping as soon as she got a firm foothold in Shanghai, and promised not to lie to her all her life.
Daqi was framed in prison and rescued by the warlord Mao Zi who was in prison. Mao Zi forced Daqi to kill the man who framed him. After that, Daqi and his good brother Xiao Pang went to Shanghai. The brave and resourceful Daqi was quickly appreciated by the inspector Hong Shouting and his wife in the patrol room and became a hit in Shanghai. Daqi went to Beiping to meet Qiu Zhi, but she was assassinated. Qiu Zhi, who witnessed Daqi's murder, chose to leave. This life of licking blood at the tip of a knife is not what she wants.
I learned that I married Daqi and accepted Po who always liked him. No matter how good Daqi was to Po, it will always be in Daqi's heart.
The middle-aged man became a big shot in Shanghai and realized his dream of that year. I happened to meet Qiu Zhi in the elevator once. When Qiu Zhi left, I looked back and I couldn't stop caring and giving up.
After the Battle of Two Wars in Shanghai, Shanghai fell, and Daqi gave Qiu Zhi and his wife a chance to escape. Lin Biao and Bao gave their lives to get rid of the traitors and protect Da Yi.
At the end of the film, Da Ju got on the bus with the dead Po and Xiao Pang, and died bravely without fear of Japanese bullets.
There are not only affection for children, but also feelings for home and country in the film. Cheng Daqi, a warm-blooded man, told himself that he must never be a traitor. Not only did it succeed, but also Lin Biao, Hong Shouting and his wife Po. Every China person with conscience will not be a traitor and die for his country at the critical moment of life and death.
Several important characters in the film are very touching and worth seeing.
