My name is Zhang Jinyu. Zhou Yu's character is "Gongjin". My sister has already used the character "Jin", so my brother might as well use Zhou Yu's character and name. There are many descriptions and sentences about Zhou Yu in ancient poetry. For example, Su Dongpo's: "Reminiscent of Gong Jin's time, when Xiao Qiao got married for the first time", and "Wanting to win the attention of Mr. Zhou, he often struck the string by mistake" (Li Duan of the Tang Dynasty) and so on. In short, "Yu" is a very good word.
