From the perspective of health, there are Yijinjing, Baduanjin, marrow washing, six-character formula, yoga, intelligent qigong, Taiji Chuan and Taiji Qigong. From the perspective of martial arts, there are Xingyiquan, Bagua Palm, Hard Qigong and Shaolin Boxing. Anything that can develop internal forces can be regarded as qigong. Stimulate acupoints and meridians through external relaxation and specific actions, promote qi and blood circulation, and let qi sink into the abdomen to cultivate vitality, but be careful not to use qi to cultivate vitality forcibly, otherwise it will be counterproductive. Let nature take its course and leave it alone. In addition, the head should be slightly raised as if there is something on the head, which is called "virtual refreshing". Don't call your chest "holding your chest and pulling your back", your hands should be heavy but not hard, your feet should be slightly low, and your lower abdomen and anus should be closed. If you practice Tai Chi, you should pay special attention to the change of reality, and relax while sinking. When I say loose, I don't mean loose. I have no strength at all. To feel resistance, all this needs the brain to command. If it is pushed out, the brain must first think about how to push it out, or slowly push it out; Or hurry to push; Whether you use force or not, you have to go through your brain first. If you want to practice hard qigong, you can't practice it like this, and you can't practice hard qigong if you practice soft qigong. Qigong, on the other hand, talks about strong inhalation and strong breathing to send gas into the body, which also has no health preserving effect. The specific methods should be practiced according to the requirements of different boxing methods.
