The Mo Dong Sect, including Cheung 3 Fung, evidently placed the blame for the suicides of Cheung Chui San and Yan So So on the members of the other five orthodox sects (although there was also the underlying cause of CCS and YSS's feelings of guilt over the crippling of Yu Doi Nam). Even the normally unvengeful and forgiving Cheung 3 Fung offered to teach young Cheung Mo Gei martial arts so he could one day avenge his parents. The relationship between Mo Dong and the other sects definitely took a bitter turn here.
And yet, a few years later, the Mo Dong Sect joined the other sects in the assault against the Ming Cult's headquarters at Gwong Ming Peak, and was still a regular participant in wulin affairs. Given the understandable resentment that built up between Mo Dong and the rest of wulin following Cheung Chui San and Yan So So's suicides, how was it that Mo Dong was willing to cooperate with the rest of wulin again?
