Is Zhan a younger sister?

Zhan Yongran and Zhan Hao Qing are brother and sister, born in a tennis family. Their father is their coach. Although their mother is not a professional tennis player, she often participates in tennis competitions. It is undoubtedly a very happy thing for a family of four to have the same hobbies. The whole family will also play doubles together. "When we were young, my sisters paired up with my parents to play doubles. When we grow up, we will draw lots to pair doubles at home, but we will not play very seriously and dare not embarrass our parents too much. " Zhan Yongran said humorously.
