Xiao's breath is the same-smile, the upper and lower lips form a small, thin meeting, control your mouth muscles, focus your breath on that small piece of tea (this tea is Xiao's mouthpiece), gently blow it away and blow it to the other end of the cup. And don't splash water (the water is very hot) so that the drum sound is easy to blow out.
Don't worry, it doesn't matter, the more urgent and tight the voice, the more uncomfortable it is. "Disturbance is miscellaneous, clarity is clear, confusion is falsetto, and peace of mind is clear."
