Every morning when I wake up, I will move my tongue until I stir up saliva with my tongue and then swallow it slowly. This kind of pharynx and body fluid regimen was later called "red dragon stirring the sea", commonly known as tongue surgery, which is to stir the tongue in the mouth, thus promoting the production of saliva.

First of all, you should be calm. Then gently stir the body fluid with your tongue up and down, left and right for 9 times, first left and then right, and stir the body fluid with your tongue to promote saliva secretion. Then, rinse the remaining saliva produced by the practice and swallow it slowly in three mouthfuls. Pay attention to send it to Tian Dan with your consciousness. When swallowing body fluids, you should giggle, but don't use too much force.
