Karate from Shaolin Temple - Kazuma Kenji (1976) - Yuen Yuen Institute, Tsuen Wan

Wu pursues the boss man to the Yuen Yuen Institute where he and Musashi get into it as Musashi mistakenly tries to protect the boss from who he believes to be the bad guy. This is also the same place where Wu meets Musashi again later and the pair are seen by the gang, leading to Musashi's capture.

The place has changed a bit over the years but elements seen in the screen shots below are still around such as the small pagodas and the archway behind the actor in the second image. However, I don't think the yellow arch seen in the last two images is still around and believe it was replaced by the current larger ornamental gateway.
