Brother Zhang Qixu. Brother Zhang Chengxu.
First of all, the word "Xu" itself means "the first sunshine" and is homophonic to "continuation", which represents a kind of continuity and eternity. My brother’s name is Qixu, and the word Qi means beginning, which represents beauty and happiness. The younger brother is called Chengxu, who will inherit the glory of the rising sun.
Hope you like it. You don’t have to use your mother’s last name, Haha
