I was in the process of making portraits for both films when I decided to go ahead and upload the credit images. There was something that I noticed about Ninja's Extreme Weapons (1987). It lists the action director as Felix Tong. Since Chiang Tao was credited as the martial arts director on its HKMDB page, I did look to see if that was one of his aliases. I did not see it on the list. Could this potentially be another alias that isn't listed for him or someone else?

Here is a link to the image I'm referring to: https://hkmdb.com/db/movies/image_detail.mhtml?id=15950&image_id=426211&display_set=eng

This is just the the credit images that I uploaded for both films:
