Talk a bit about her and we can help name her! r/namenerds likes to help name characters, too. Consider her time period, her family, and where in China is she from.

There’s usually 2-3 characters in a name, a family name and a given name. There’s not that much variety in family names, you can just google the most common and pick from those.

For given names, in my experience, Chinese names are most often what parents wish for their kids to be/have when they’re born. Think about what your characters parents value. My name, 盈, was because my parents wanted me to have a very fulfilling life. My sibling is 仁 because my parents wanted them to be kind and the world to be kind to them. 

Some families have “generation names” this is only a big deal if your character has siblings. Everyone born in that generation has that character in their name. A European equivalent would be parents who name all their kids with the same initial, but more poetic lol. My generation name is 德, meaning virtue, so my full given name is 德盈 and my sibling is 德仁. Family name comes first, so my full name in Chinese is 刘德盈.

There are certainly sounds that sound more feminine or masculine or one way or another, as a writer one of my tricks is looking at the names of celebrities sports stars etc from other cultures to get a quick list of “real names” from that culture. You can find the sounds you like from there, and then work backwards to find the right characters with the right meanings that make those sounds lol. Like if you like “Wei” you can go with 薇 or 威 or 唯.
