The Young Rebel - David Chiang (1975) - Sifu Chi Wai's Wing Chun School, Mongkok Road

Here's a location I never thought I would see again. In the film, this is the location of Gen Lai's kung fu school with his sifu being portrayed by Yuen Siu-tin ("Beggar So" from Drunken Master for those who need reminding). Long term readers may remember this place was also used for Bruce Lee True Story (aka Bruce Lee the Man, the Myth), so you can click the link and read all about it there. It was located at 28 Mongkok Road.
