I guess this DVD was authored from an old export print (the San Francisco-based distributor logo at the start being my main evidence!),
While I don't recall this logo (Incidentally San Fran is where I first paid to watch it), the credits still wreaks of being messed with. Nothing really wrong with that & not an issue so much as to the origins of the print or even how the title has evolved (just add an AKA) as much as WHO really directed this film. I've always known it to be Pan Lei. My issue is these credits puts that known fact into question. I might cross-reference the directorship issue here and with historical listings in other DBs, versions, publicity, etc. and mete out the facts. This one's easy; there's a lot of stuff on it. Just look at the images on file with the entry. I recall Heinz having a 35 year old Singaporean flyer for this film. PM someone who knows Chinese here to decipher it and then decide. In the end, nothing wrong with sharing the director's credits I guess.
Like I said before in so many words for me, incumbency carries a lot of weight on these matters so whenever there's seemingly new facts to counter well established ones for a film (that's been around for 36 years no less!), the editor has to stop to recognize the foundation of previous data first and then address validating the new stuff and how it challenges the old. Sometimes, things aren't what they seem to be (especially if it's new). If there are no old stuff, then stake your claim.
