In the ancient intimate contact of Mahjong 2, Liu Chengze was bullied and discriminated against because of albinism, and was not liked at home. But in Lao Chaofeng, he is recognized and valued. He became the general of Lao Chaofeng, and owned one of the five cans, the Xiliuying jar of Zhou Yafu station troops. People send the nickname "Xiao Bai".

He is an important part of the forces of the old Chaofeng, suffering from albinism, being bullied since childhood, being recruited by the old Chaofeng, and being in charge of the "westward camp" is considered to be an important position. However, he is also a little naive in fighting with medicine or making a wish, and he is the real clique of Lao Chaofeng. However, a little different from the first film, Shenyang's "big childe" did not appear, which was a bit unexpected.
