Is it a person’s name? Is it a Chinese name?

Chinese names are actually easy to translate.

Just capitalize the last name: Xi as Xi, and the first name: Ding Zhu as Dingzhu.

Yes Written as Xi Dingzhu

Note that the last name should be capitalized and separated from the first name by a space! If the name is one character such as Xin, it should be written as Xin. If the name is Xinxin, it should be Xinxin. The second character should be lowercase and follow the first one
