Sang was born in Hong Kong, the son of Chow Yuk-mui (Louise Lee) and Kiu Sum (Lee Kwok Lun). Due to Kiu Sum refusing to marry Chow Yuk-mui, Yuk-mui decided to take Tin-sang to Foshan, China to start anew. In Foshan, Yuk-mui got married with Law Fu-shing (Lau Kong) and gave birth to Wai-sun a few years afterwards.
Not long after, the family of four decided to cross the border to start a new life in Hong Kong. The family of four eventually got separated with Tin-sang ending up in Hong Kong, while Yuk-mui, Fu-shing, and Wai-sun ending up in Macau.

He has a girlfriend named Rachael Cheuk (Linda Chung) whom he is willing to do anything to fulfill her dreams of opening a fashion store. In order to achieve his goal, he seduces Favio (Ankie Beilke) and uses her in the process. In addition, Tin-sang also has an ambiguous relationship with a triad member named Keung Yung (Louis Cheung) who later caused Tin-sang to end up in jail.
Wai-sun, who is very simple-minded, only wants to live a peaceful and comfortable life in Macau. He is good friends with Yiu Man-ying (Krystal Tin) and Lung Fei (Louis Yuen). In order to avoid his abusive father (Fu-shing), Fu-shing works with his mother (Yuk-mui) at a restaurant. The lives of the two brothers, Tin-sang and Wai-sun began to change after they meet up again. The two brothers in the series will go from 20 to 50 years old.
