In quite a few wuxia stories, especially Gu Long's, we hear of a "Dim Chong" Sect and meet some of its members. The sect shows up from time to time, but is almost never considered a major sect like Shaolin, Mo Dong, Ngor Mei, Kunlun, or the Beggar's Union. What's the story on this Dim Chong Sect, and does it have any notable martial arts or members?
