I do bring along dried mushrooms and hae bee with my lup cheong
... and I cart along things like spring onions and cabbage too ...
I bring along things like sambal and belachan also, cos these can
keep without refrigeration but these doesn't last beyond the first
three days ... after that, it's down to packets and cans ...
that's no issue when backpacking of course ... 
your sifu got to the level where he's started foraging in the
jungle already ? ... I mean, seriously ? ...
