He has been nicknamed "Super Dan" by his fans.

In his early years, Lin was encouraged to learn to play piano by his parents, but chose to play badminton at the age of five. He joined the sports troop of the People's Liberation Army at the age of 13 and has been part of China's national badminton team since 2001 when he was 18.

Wakin Chau (born 22 December 1960) is a Hong Kong-born Taiwanese singer and actor. Chau's popularity has spread throughout Taiwan, Hong Kong, Mainland China, and parts of Southeast Asia. He was known as Emil Chau through the 1980s and 1990s, and by 2000 he reverted to his given name Wakin. As of August 2007, he has released more than 40 albums and held several international concert tours.

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.

Wakin had high hopes to establish a career as a recording artist, and he actively sought out contacts in the music industry. But a persistent lack of interest eventually led him to give up trying to become a performer — instead, he could sign on as an assistant producer at Rock Records, where he wrote marketable pop songs for other artists.
