In 1936, the third young master of the Kong family, the head of the Eight Great Families of Tianjin, watched a play at the Guangdong Guild Hall in Tianjin, where the commander of the Tianjin Military Police shot and killed the female dan Sai Xishi. In a hurry, the third young master said casually that he wanted to avenge Sai Xishi and kill Kawaguchi within three days. With the help and encouragement of the people of Tianjin and people from all walks of life, the story of the commander of the Japanese military police in Tianjin was finally blown to death.
