Hey guys,whats up?

Can you give me some hints about how to properly breath depending on what i am doing in kung fu? For example:

1) Correct way of breathing while training soft styles (tai chi,bagua,etc)

2) Correct way of breathing while training hard styles (BSL,shaolin quan,hung gar)

3) Correct way of breathing to the make the most of a technique's power.

4) Correct way of breathing so you can conserve energy (in training or combat)

And such...
