From what I've heard, the meaning of a Chinese name is usually gender specific. Names that mean brave, strong, ambitious, etc. are usually given to males while names that have to do with beauty, peace, flowers, and virtue are given to females. This was true in ancient Chinese culture and might not be as common today, but you probably won't meet a guy who has a name that means flower.

I know the name is usually given to a boy must sound strong and muscular, for a girl the name sounds soft and feminine. My niece name is 珍怡 (precious, harmony), I also know characters like 怡, 华,安 can apply both male and female name.

I know that some of the english names the guys call themselves are female names and some gals, call themselves male names, maybe it is because it doesn't apply to Chinese names!?

Some are gender specific but there are males with female names and vice versa. Often the name is supposed to be a masculine name or delicate and feminine name depending on the gender. However, there are instances where a child will have a name that does not fit their gender as a nod to ancestors.

Most names r gender specific.
Like my name. Na is really a common name for Chinese girls.

But there r also many names both male and female can use. Like lei, miao...

Also there r some people who use opposite gender‘s name...

IS there a way to tell? In English female names just sound more effeminate. But, only a native speaker, or someone who's spent alot of time in the west would have a sense for it.
