HYS' bias toward OYK during the marriage proposals and subsequent contest between OYK and GJ is quite strange and puts HYS in a poor light.
First, HYS fancies himself a man too cool for the world. He hates the Confucian code of social behavior and conduct (li fa), therefore one would think that he would be progressive enough to let his daughter choose her husband, but he imposes his will on her just like any regular daddy-o on mainland would.
Second, he supposedly loves his daughter to death. Yet he is willing to marry her off to a guy whom he knows is a bad guy while also knowing that HR would probably kill herself or run away. I believe that he is actually trying to get back at HR for running away and disobeying him.
Third, his main objection to GJ is not because he killed his (HYS') disciple or have had several run-ins with Mei Chao Feng, but rather that having a dumb son-in-law would mar his reputation and embarrass him.
HYS comes off as a pretentious petty hypocrite.
