Men Don't Cry (2007) - Evil Kin
With the support of the head of the Police Authority, Guangzhou’s top villain Ho Kei-Kin (Dayo Wong) has been riding roughshod over everyone around him. He is so manipulative that he has explored every possible means in his fight for a house with the buck-toothed owner Ling Yuk Tsui (Cecilia Yip).
However, he was originally a kind-hearted person. His change of heart was due to him being mistreated by his father back when he was a child. His father once nailed him inside the coffin, which led to his fear of being trapped in the dark. When he grew up, his father left the town with one of his many mistresses and her son. When Kin went to confront his father, the father retorts and says that Kin wasn't really his biological son, saying that some stranger is his father. His father also said that he was glad to have a son who is more skilled than him and that Kin is nothing but a weakling to him. After that, he left by boat. Angry by this, Kin cursed at his father, his mistress and their son, saying that they won't live to regret this. When he tried to redeem himself by fighting the town's crime lord, he was defeated by not only the crime lord but also the townspeople. Fed up with the town, he causes chaos to the town by wrecking and burning some stalls. As the crime lord and the townspeople were about to subdue him, one of his henchman told him that the boat that carried Kin's father exploded and that everyone on that boat died, including his father, his mistress and his son. Kin said that he was happy that happened because they had insulted him and that his prophecy of them not living to regret it had come true. He also declares that he won't go by his given name. He will only go by the nickname Gan Yan-Kin (Bully Kin). He decided that to get through life, he must treat others really badly as they have treated him.
