He's sleazy! He loves power & gold and doesn't like recognizing his numerous illegitimate sons and daughters! Jin Guangshan is a trash human being, but he wields a ton of power and influence. Not above keeping evil around to help him do his bidding. Really wants the Stygian Tiger Amulet.
"Therefore, from ladies of distinguished statuses to prostitutes in rural areas, if he could get his hands on one, he wouldn’t miss the chance. And, although he enjoyed casual relationships and flirted everywhere, having an uncountable amount of illegitimate children, it was extremely easy for him to get bored."
Also the father of Jin Guangyao's wife, Qin Su.
