Choose the highest and purest place, take the most clear and harmonious energy, breathe it in through the nose, and let it rush to the dantian. It enters through the mouth and rushes into the abdomen. Three, five or seven are all fine. The most detestable things are unclean ground and unclear energy. Be cautious and careless! The above points are not fixed in number. When performing the exercises, one should focus on naturalness and not slightly harm the qi. The best way is to follow one's heart's desire. When the mind is present, the qi is present; when the qi is present, the blood flows smoothly. If there is no question for a long time, the effect will arise, but it is also a helper for the year.
