The phrase 'ด้วยกัน (dûai gan)' is a commonly used term in Thai language that expresses the idea of doing something together with someone else, or having something occur together with other things. It is typically used at the end of a sentence after a verb to indicate the collective or shared nature of an action. Also, it can be used in conjunction with expressions of location to denote that multiple things or people are in the same place together.
