During the Republic of China, Shanghai movie star Cheng Yanzhi and female screenwriter Song Chenxi met by chance. Song was the daughter of a wealthy businessman in Tianjin. Although she had a good relationship with Cheng, she went to study in England because of family fate. A few years later, when he returned to China to teach, the two met again. After the victory of the Anti-Japanese War and the imminent civil war, Song was listed on the Kuomintang list for writing progressive articles and was forced to leave Shanghai for Hong Kong. In Hong Kong, Song reunited with his old classmate Zhao Wenbo, and Huabei Yuan also used the restaurant as a cover to start working. In the end, Song and Zhao jointly participated in the two airline uprisings, and later returned to the mainland to join the construction of New China; Cheng stayed in Shanghai and handed over the company to the public and became a literary and art worker in New China; Huabei Yuan later took the initiative to assist the underground party in Hong Kong many times, and later returned to work in the mainland to assist the public security in arresting remaining spies. In old age, he used his connections in Hong Kong to actively participate in the construction of Shekou. Several people have chosen different but bright paths in the great era.
