Secondly, I personally think that the meaning of a name should be valued first, followed by pronunciation. "Ji" is ambiguous, and it is best to use a flat tone for the last word.
The following are the names that I feel better about. I hope they will help you.
Male: Zeng Ji, Zeng, Zeng Jifei, Zeng, Zeng Jichu (date of birth), Zeng, Zeng Jichao, Zeng Jihang, Zeng and Zeng Jikai.
Female: Zeng, Zeng (birth season), Zeng, Zeng Jifei, Zeng, Zeng Jiyun, Zeng.
