With reference to grass, sometimes it’s the girl who is the grass, as the old proverb “老牛吃嫩草”(lit: old cow eats tender grass)…if the girl is the grass, I think we can all guess who the “old cow” is without too much of a mental leap…

As for names with花, I think it’s definitely safe assume that花is a girl’s name! However, as far as I know (in Taiwan at least) 花 (flower) fell out of fashion a few decades ago. It’s an old-fashioned name, and also one with strong sexual overtones (not surprising given all the sexually charged slang words and idioms it has produced).

I know this anecdotally, having taught a woman whose given named contained the character 花. As a 40 year old woman, she said that she hated her father vehemently for a long time for having given her this name (the steal glint in her eyes made it clear that she still hadn’t forgiven him), but admitted that it was one of the factors that drove her to be better than everyone else. She told me, “If I got first place on the test, no one would dare to laugh when the teacher called my name, because it was the first name spoken.”

There are girls named “hua” in Taiwan, but it is this hua – 華, used as a noun in “China” (中華) or in “Overseas Chinese” (華僑), or as an adjective (豪華) meaning “luxurious”.

Literal translation: “Don’t pick wild flowers on the roadside.”

Means: Don’t go flirting around.

Suffice it to say these are hard to explain to a young child.

means go to such a restaurant, in where guests can have fun with the femail escort while they are eating&drinking.

Normally, 花and草 both are girl’s given name. These name are very traditional name, I think around 15 years before,parents will name their daughter “花”or “草.

I suppose becasue “flower” and “grass” are all stand for effeminate things.

For example: 李春花， 张春草 （spring flower , spring grass）
