Professor Yang Xiaojing is a professor and doctoral supervisor in the Department of Mathematics. He is very popular in Tsinghua University, and many students want to take his advanced math class.

Yang Mi was named after her uncle, who is a professor of mathematics, so the idea of naming her couldn't help thinking about mathematics.

Yang Mi was born in Xuanwu District of Beijing (merged into Xinxicheng District of Beijing). His father Yang Xiaolin is a policeman and his mother Yang Chunling is a full-time housewife. Because all three people in the family are surnamed Yang, which is the cubic of "Yang" (the result of power in mathematics is called power), she was named Yang Mi.
