Please give me a Japanese name from a professional who knows Japanese.

Because your surname is Li, choose one that looks more related to "wood". For example:

Morita Fujimoto Akimoto Aoki Fujimoto Fujimoto

Name:

Your name sounds very Confucian, so the first name that comes to my mind is Shengzhengren.

I prefer other names: Kazuki Tuohai Tuohai Naoki Lian Renshun.
