How do you say are doing in Thai?

The most common and polite way to say "how are you doing" in Thai is:

สบายดีไหม (sa-bai di mai)

This literally translates to "Are you well?" and is used as a general greeting to inquire about someone's well-being.

Other variations:

* เป็นอย่างไรบ้าง (pen yang rai baang) - This is a more casual and informal way to say "how are you doing," literally translating to "How are you?"

* สบายดี (sa-bai di) - This is used to respond to "how are you doing" and means "I'm well."

It's important to note that the tone of voice and body language can also convey different meanings. A friendly smile and an engaged tone will make your greeting sound more sincere.
