What are the names for boys that have a belt in front of them?

Zi Qian, Zi Kai, Zi Xiang, Zi Ming, Zi Ran, Zi Yao, Zi Qi, Zi Kuan, Zi Rui, Zi Mo,

Zi Xiao, Zi Hao, Zixuan, Zilei, Zibin, Zipeng, Zixu, Zijun, Zibo, and Ziqi.

Why do we need a belt in the middle? Such a name is difficult to choose

It’s just my own careful thought, I hope I can adopt it
