Chu Shong Tin (徐尚田, born 1933) was the third student of martial arts teacher Yip Man in the discipline of Wing Chun, and remained at Yip Man's school to become his senior instructor.
Chu Shong Tin was nicknamed "The King Of Sil Lim Tao" for his deep understanding of the first form. Chu places a great focus on this form in his teachings. He places a great amount of emphasis on relaxation during the form, minimum to no use of muscular power. Chu Shong Tin teaches an internal style of Wing Chun Kung Fu.
He moved to Hong Kong in November 1949, started learning Wing Chun informally in September 1950. The 17-year-old Chu was a secretary at a restaurant at whose premises Ip held classes, which he audited. Chu became Yip's formal student in January 1951. As his health was not good, he took a concept-based form of the discipline. Today, he teaches selected students from all over the world, communicating with English speaking students through body language and hands on demonstration, or assisted by other Chinese students, since he doesn't speak English. Though he considers himself retired, he accepts students for the purpose of passing on his understanding of Nim Lik to ensure its survival.
