Your innate deficiency of vital qi and the disharmony of yin and yang circulation in your body the day after tomorrow lead to excessive discharge of Yuanyang and retention of Yin Qi. During the great cycle, Yin Qi will naturally react when he gathers in his mouth. Find a way out for Yin Qi and give your teeth a crooked jump. All you need to do is let Yuanyang come out a few times more, and then you can be a great success and become a pure yin body.
