I guess it is a kind of self-rise flour. I suggest you check the integrents and see if it contains soda. If so, you won't need anything else. Just mix the flour with water, and make "bao zi", then stream "bao zi".

Sorry, I just reallized what you bought is powder, not flour. You'll need to check the package carefullly for instructions.
