Wakin Chau was born in a rice store owned by his family in Sai Ying Pun, Hong Kong. Growing up as the fourth son in his seven-member family, Wakin learned to play the guitar when he was about 13 years old. In 1979, he left for Taipei to major in mathematics at National Taiwan University. During his college years, he sang and played folk songs in local coffee shops. This activity was a tradition among NTU students, and it is how Wakin learned to sing in Mandarin, which would be key to his future as a music-maker in Taiwan.
　　

Shortly before his music career took off, Wakin the record producer met an American girl named Constance Woods, whose father was in Taiwan as a Fulbright scholar. Seeming to have plenty in common (including birthdays only one day apart) Wakin and Constance began to date, got engaged and then on 16 November 1986, they married in Taipei. Four months later there was another ceremony with family and friends in the United States of America on 14 March 1987. They have a son named Andrew and a daughter named Anya.
