Both are good.
When the word Han is used as a girl’s name, it often means connections, wealth, etc., while when the word Han is used as a girl’s name, it means luck, harmony, etc., so Han and Han are used as girls’ names. The implications are very good.
Giving a name to a girl is different from that of a boy. Most of the time, what we want is not domineering, but good-sounding and auspicious. Therefore, when naming baby girls, we try to choose those with good meanings and good-sounding sounds. Of course, try not to choose those uncommon words or tongue-twisting words. After all, the most important thing in choosing a name is smooth and auspicious. For example, Han and Han are two characters that are more suitable as names for girls.
Notes on naming:
1. Avoid the same initial consonants and final rhymes of the surname and the given name, such as "Wang Wenwei" and "Bao Bobang".
2. Avoid homophonic sounds of names with offensive words. Names such as Li Si, Han Yuan, Shi Shi, Du Zida, etc. are very elegant in meaning, but they are easily read as "you die", "crying injustice", "dead corpse", "big belly" etc. in spoken language.
3. Avoid names with the same four tones, such as Liu Jingxuan, which has three tones, and Zhang Xiangshuang, which has one tone, which makes it difficult to pronounce.
