1. Nenniu Wufang is the nickname of Tieba masters for Fatty Wang, Zhang Qiling, Wu Xie, Jie Yuhua, and Black Glasses.

2. Because Wu Xie has a square face, he is called Nenniu Wufang. Although Fatty Wang is not very handsome, his wit, bravery, and mainly humor in exploring caves have covered up his shortcomings of not being handsome, so he is also on the Nenniu Five-Party Team.

3. The source is the Easter egg in the stage play "Crescent Hotel" and Fatty Wang's Day. Probably Xiaohua said that you three Iron Triangles don’t matter to me here, and then Fatty said: Then let’s give it another name, Sanxian Yimian, how about the Four King Kongs? No, no, then Nenniu Wufang!
