Soya bean water is very easy to make , not a
problem at all .
Tau geh cannot be made , it has to be grown from green
beans . Its actually green bean sprouts , to make bulk quantities
you need alot of space to grow it .
Growing mushrooms ... i also want to know how to grow
edible ones .
Above 3 stuff do not need business skills to make . Just
some knowledge nia . Esp soya bean water and tau geh .
Please do not make things look difficult or complicated
when they are actually very easy to do .
i think his main question is owning/running his own factory and
have his own product.
