* 中国 (Zhōngguó): This is the official and most common way to write "China" in Mandarin Chinese. It literally means "Middle Kingdom."
* 中華 (Zhōnghuá): This is a more formal and poetic way to write "China." It is often used in official documents or literary contexts.
So, both "中国" and "中華" are correct ways to spell "China" in Chinese characters, but they have slightly different connotations.
