What does Shen Dantian mean? Mr. Hao Shaoru said:
"Breathing air to the abdomen without floating is called qi sinking into the abdomen." Mr. Ma Litang, a Xingyi boxer, said: "The ascending is clear and the descending is turbid, and the qi returns to the umbilicus. When inhaling, the perineum is gently lifted, the air rises to the top, and it relaxes when exhaling, and the air sinks into the navel abdomen. "
Hao Jiajun, a famous Tai Ji Chuan, said: "The points in the chest are empty and the stomach is heavy." In my humble opinion, the sky is just abdominal breathing, the diaphragm moves up and down, combined with the opening and closing of boxing.
When inhaling, the diaphragm moves down, the lungs expand downward as far as possible, and the ribs are slightly expanded, but the ribs should not be lifted up, and then the anus is raised below to contract the kidneys and hold the internal organs. When exhaling, the diaphragm rises, the two sides converge inward and downward, the internal organs naturally droop, and the true qi in the chest flows down the ren meridian into the abdomen, forming a situation in which the heart and kidney intersect to replenish the fire of the life gate. The chest, back, shoulders, waist and buttocks are always relaxed, while the abdomen is heavy and full. Take a deep breath and breathe evenly for a long time to achieve the requirement of "innate qi should be stable and acquired qi should be smooth".
