Possible Split: Cheung Faan (1)

Just watched COCKTAIL with Endy Chan and Race Wong tonight and in looking up the writer, discovered a possible discrepancy: according to our DB, Cheung Faan, the writer of this film and the likewise decent TRUTH OR DARE: 6th FLOOR REAR FLAT wrote these two youth-oriented films after a thirty-nine year absence from the industry. That's just doesn't seem right...

I can't say for sure, but hopefully someone can provide further evidence of the need for a split here.
