While he was on the run from Sai Mun Chui Sheut in LUK SIU FUNG, Vol. 5 (THE HAUNTED VALLEY), Luk Siu Fung encountered a young man by the name of Yip Goo Hung, who was the younger cousin of the Sword God Yip Goo Sing. Yip Goo Hung was a Sai Mun Chui Sheut-wannabe. He dressed and acted like Sai Mun Chui Sheut, and his goal was to become a better swordsman than Sai Mun Chui Sheut and kill him. Yip Goo Hung eventually committed suicide in despair after being easily defeated by Luk Siu Fung, who himself believed that he could not last one move against Sai Mun Chui Sheut. Yip Goo Hung knew that if even Luk Siu Fung couldn't defeat Sai Mun Chui Sheut, then he (Yip Goo Hung) had no hope at all.
Question: why did Yip Goo Hung choose to impersonate Sai Mun Chui Sheut and not his famous cousin, Yip Goo Sing? Logic would seem to dictate that Yip Goo Hung would idolize and imitate his own cousin, not the man who killed him.
