If you meet Sundanese people and you want talk about everything with them, first yout can say "Hi" for greeting or opening the dialog.
The meaning of 'hi ' in Sundananese language is "héy!". In Indonesian that is "hai!".
Example:
Mr. Adun : "Héy!" (Hi!)
Mr. Ujang : "Héy!" (Hi!)
Mr. Adun : "Sampurasun! kumaha damang?" (Greeting! how are you?).
Mrs. Ujang : "Rampés! Pangésto." (Greeting too, I'm fine).
