* 中国 (Zhōngguó): This is the most common and formal way to refer to China as a country. It literally translates to "Middle Kingdom."
* 中华 (Zhōnghuá): This is a more poetic and traditional way to refer to China, often used in historical contexts or to emphasize the cultural aspects of the country. It literally translates to "Central Flower."
So, when in doubt, 中国 (Zhōngguó) is the safest bet!
