Bruce Tuan's 7 Promises (1980)
The Flute Player of Wrath (1981)

That is very interesting. I had looked into the Ou-yang Hung pseudonym in the past myself and these were my conclusions:

[...] "Bruce Tuan 7-Promise" and another movie called "The Flute Player of Wrath" both credit Ou-yang Hung as director, which looks like a pseudonym since there's no other credits to his name. Since the IFD poster [of Born of Fire, the dubbed version of Bruce Tuan 7-Promise] credits "Ulysses Au-yeung", that is, Tsai Yang-ming or Ou-yang Chun, I guess it's safe to say these two were directed by him. One VHS cover of "Shaolin Drunken Monk", which was definitely directed by Tsai Yang-ming, also credits "Ou-yang Hung".

I wonder why they both used the same pseudonym at different points, considering that they had apparently never worked together.
