(Ricoh GRD IV)
Time for learning some Cantonese. "Dadha" is a colloquial expression for small talking, where "ha" is an universal exclamation morpheme in Cantonese to give the sense of a fleeting moment, a quick while, a short duration or being casual. "Tang" is to listen while "Tangha" may mean to hear casually. "Taei" is to look while "Taeiha" may suggest to take a quick look.
By the way, "Dadmugah" means "What are you 'small talking' about". Oh, I really like today's shot of these three chaps "dadha" at the red traffic light even though they "dadmugah" was unknown to me.
