Also, there other movie credits missing in HKFA, vice versa.

Need your help.

I think this might have something to do with the whole issue of the two different cuts, the other being the version released as The Invincible Power of Kindness. I'll try and grab those credits as well and see if there is a difference. Maybe that will give an idea?

Invincible Power of Kindness

Uploaded credits from Invincible Power of Kindness

Yes, there were 2 versions of this movie, and several supporting characters were played by different actors.
Fixed Ye Hui last character.
Zhang Xu-Zheng, added alias.

to be continued...

2nd part:
Removed Guan Zhan-Wen and (it was my error)
I cannot remove "Ge Jian-Jun". According to the HKFA this "actor" exists and appeared in another movie called "Celebrity of the Back Alley". So this "inverse duplication" must be allowed although it is probably the wrong name is Wong Tai-Hung.
Yuan Jiu / Fa Pak Fung same case.
Xu Huan-Shan / Hui Dik-San you are right. Fixed.
