That movie has a lot of King Hu touch (and many actors of his regular cast, since the director was assistant director for King Hu twice). Found Tsang Chiu and probably young Jason Pai Piao as uncredited bit-part players

The old man probably must have been kind of prominent in his career I asume (So maybe he is Chan Ming-Loi ?)

Thanks for your new cast pages.

ID/added Chen Shih-Wei.

Your Tsang Chiu ID looks for me more like Yu Chung-Chiu:
