Just came across an old review of this in my files and noted that, while I couldn't decipher the director's full name, it does NOT appear to be Tenky Tin Kai-man, although he is credited on the VCD sleeve.

The on-screen directing credit would appear to be Lee Kwok-??? (have never been able to make out the last character, nor does it match anyone in the database). I still can't post screen grabs so perhaps someone else has this little cheapie in their collection?
The only name in the DB that comes close to matching the last character is "Kiddy" Lee Kwok-leung, but it seems odd that a props man would graduate to directing (though stranger things have happened):

Could Tenky Tin have used an alias, perhaps? Otherwise, his Chinese name appears nowhere in the opening credits.
