Lok Yiu (Lok Yu) began training under Yip Man in 1950 after meeting him through Lee Man, secretary of the Hong Kong Restaurant Workers Union. There were only a few students then, one of them being the late Master Leung Sheung.
He trained intensively under Yip Man for seven years before becoming one of his instructors. He established his own school at Sham Sha Po in 1961.
Lok Yu passed away in February 2006 and is sadly missed by his students and Wing Chun brothers.
