Depends on what you practice. If you practice Tai Chi or have a small belly, you will have a big belly. You practice Qigong, Baduanjin, Wuqinxi, Yijinjing (Note: This Yijinjing is not so fantastic, it was created by Li Jing, only 12 style, which can relax muscles and promote blood circulation, and long-term practice can benefit qi and nourish energy. But it can't stand his scrutiny. Not a real martial arts spirit qigong. ) and Taoist qigong, I still remember a passage. Listen carefully, there are nine tricks in the road. The nine orifices were originally at the tail point, and the tail gradually descended along the spring. When I went up, I passed Baihui slowly, but Baihui didn't eat mud pills. Mud pills return to the back and gradually sink into the abdomen. The longevity gas field lasts forever. Almost all Buddhists focus on meditation and epiphany. It is not easy to practice, and it is said that Huigen is clean. There is nothing in my heart. Similar to Taoist inaction. It is only a personal practical opinion, and has nothing to do with others.
