Yip Man Life in Hong Kong Initially, Yip Man's teaching business was poor because Yip's students typically stayed for only a couple of months. He moved his school twice: first to Castle Peak Road in Sham Shui Po and then to Lee Tat Street (???) in Yau Ma Tei. By then, some of his students had attained proficiency in Wing Chun and were able to start their own schools. Some of his students and descendants sparred with other martial artists to compare their skills and their victories helped to increase Yip's fame. In 1967, Yip and some of his students established the Wing Chun Athletic Association (?????). The main purpose of the Wing Chun Athletic Association was to help Yip tackle his financial difficulties in Hong Kong. Yip Man was said to have regularly used opium. One of his former students, Duncan Leung, claimed that Yip used tuition money to support his opium addiction.
