Start credit

Changed writer: according to your credits, Ku Lung does the script, and not the story, of the film.

Changed producer and presenter.

Added planner, prod. manager, cinematographers, music, art director and costumes.

Also found an interesting data: Cecilia Yip appears in the movie, 5 years before our first credit, and with another name... Li Sze Sze ( ) confirmed in WebPAC and in a lot of chinese sites:

but at the same time they say she debuted in movies in 1982...

Anyone can confirm me if she appears in that movie?
(for the moment, I added her.)
