1920S.
There is Baishishan in the south of Jiaohe County, Jilin Province, and there are two families on the street. The family's surname is Guo, and the family's surname is Zhou. The two families have a close relationship and are family friends.
The wives of both families are pregnant. The two heads of the family are drinking and talking, and they want to get closer and closer: if they both have girls, they will become sisters; if there is a boy and a girl, they will become husband and wife; if they both have boys. That is sworn brotherhood.
When the time was right, the Guo family gave birth to a boy with a tiger head and a tiger head, named Guo Lixin. More than twenty days later, the Zhou family gave birth to a son. He had delicate features and beautiful eyes, and named him Zhou Youwei. The two families congratulated each other.
The next year, the Wang family in the same village gave birth to a daughter, named Wang Yonggui.
Guo Lixin, Zhou Youwei and Wang Yonggui studied literature under the same old scholar, and also practiced martial arts under the guidance of a well-known local master. Zhou Youwei was slightly better at literature than Guo Lixin, and Guo Lixin was better at martial arts than Zhou Youwei. Wang Yonggui's level was between Guo and Zhou, but her father was a Chinese medicine doctor and she also studied Chinese medicine with her father, so she was more skilled than Guo and Zhou.
This book is about the love and hatred between Guo, Zhou, Wang and their children in the world.
