(3) Health care methods. Mental conditioning: people with this constitution are impatient, often upset and irritable, which is the reason why yin deficiency and fire are flourishing and disturb the gods. Therefore, we should follow the Dafa of "being quiet and empty" and "keeping the spirit inside" in Huangdi Neijing.

According to the principle of "nourishing yang in spring and summer", eating mutton soup every volt in summer is to strengthen the yang of the human body when the world is prosperous.
