less than happy subject, but i was curious to know more about the traditions involved when someone's sifu passes away. my understanding thus far is that immediate students (todaimui) wear a black armband around one arm for a certain period (one year or three, i cannot remember, and i don't know which arm), and that grandstudents (tosuen) where a white armband, but i do not know the typical period, or if one is set.

can someone give further explanation on this?

thanks.
