Wen Chengyu is the late-born son of Wen Congwen and Cheng Ruzhu, and his personality developed to be quite overbearing. But strangely enough, his only nemesis is Ping'an.
Every time he gets so mad at Little Douding that he jumps up and down, but in the blink of an eye, the two, despite their significant age difference, are hugging and whispering to each other again, truly living up to the name of cross-generational friendship.
Among many uncles, Ping'an likes him the most. By his values, he explains it like this: Uncle Wen Chengyu is generous; he keeps all the good stuff for himself and is his good buddy.
The elder Mr. Wen and Mr. Cheng were sworn brothers. Of course, in their literary wording, they were inseparable friends.
