Formal:
* 拥抱 (yōng bào) This is the most common and formal way to say "hug." It literally means "embrace" and is often used in writing or formal speech.
Informal:
* 抱抱 (bào bào) This is a more informal and affectionate way to say "hug." It literally means "to hug" and is often used between friends or family members.
You can also use the phrase "抱一下 (bào yīxià)" which means "hug once" or "give me a hug" and is a more direct way to ask for a hug.
The best way to choose which word to use depends on the situation and your relationship with the person you are speaking to.
