Appropriate
Avoid when
You can say "wǒ lái guo Zhōngguó" (我来过中国) or more commonly "wǒ qù guo Zhōngguó" (我去过中国).
It is pronounced "wǒ lái guo Zhōngguó" with the third tone on wǒ, second tone on lái, neutral tone on guo, first tone on Zhōng, and second tone on guó.
Use "guo" after a verb to indicate that you have had the experience of doing something at least once in the past. It is often used to talk about life experiences, like visiting a place.
