Is it true that a release date (HK) exists for this film? Is it complete to the film end?
There are magazine images uploaded, but this is information from the beginning of the production, right?
Does anyone have any information?

I have no information, but something is strange when a magazine published in June 1971 reports the begin of the shooting of a movie (開拍) already released in January 1971. And there's no doubt about the release date of the magazine:

I removed the date, thanks

also i changed the date to 1971, i'm open to opinions

Thanks to both of you.
Well, it looks like it is definitely a Shaw Bros film.
I will look into it, and the fact that it is a Cheng Chang-Ho film may give me a clue.

I will wait for more information.
