4 focus on tapping knees and elbows to detoxify, roll up sleeves, expose the elbow joint of the arm, and tap the left elbow joint with the palm of your right hand (mainly inside). When you feel sore and tired, change to your left palm and pat around your right elbow. After shooting the elbow joint, clap your palms around your knees. Repeatedly tap hard for more than 10 minutes. You don't have to think when you slap. You can fan hard when watching TV or chatting. It can be said that it does not take up time. People who exercise in the early stage, especially those who have physical diseases, generally have rashes, which is a phenomenon of clearing away sick gas and turbid gas in the body. Don't worry, you won't leave scars on your skin after exercise. After you can't get spots after exercise, pat along the palm and calf, and keep exercising until you can't get spots on your limbs. The exercise time can be shortened appropriately. Through this exercise, it will be better to practice the cultivation of internal qi after eliminating the evil and turbid qi in the body. Imagine if there is sewage and muddy water in the pipe network, you don't discharge it first, but you just keep adding fresh water to the water source to make it circulate in the pipe network. Then for a long time, the water in the pipe network was half clear and half turbid. If the mud is drained first, and then the water is added, the effect is obviously different. Therefore, in the movement of beating and dredging meridians, we should pay special attention to slapping around the elbows and knees of the limbs, and take the elbows and knees as the outlets for discharging turbid gas in the body. Because the elbow and knee joint are the places where the twelve meridians combines, according to the original chapter of Ling Shu's Nine Needles and Twelve Needles: "Join in." That is to say, in the aspect of meridian flow, it seems that rivers from all over the world meet and flow into the sea. Accordingly, the menstrual gas flow at the joint point is also relatively large, and it is easier to expel turbid gas from the body by choosing this place. There is a joint point in the twelve meridians of the whole body, and it is considered that the joint point plays an important role in the treatment of visceral diseases by acupuncture, massage, cupping and other external treatments. In the solar energy health care technology, the vibration of the first section of the meridian-pulling and pulse-dredging combined with the idea and train of thought of discharging the diseased gas to Yongquan point can also discharge the turbid gas in the body. But for beginners, it is more effective to beat around the elbows and knees of the limbs to expel the turbid gas in the body. The whole exercise process of solar energy health care technology is a metabolic process, which discharges the turbid gas produced in the body and constantly increases the fresh gas to nourish every cell in the body. This is a process of saying goodbye to the old and welcoming the new. Special note: the first process of internal qi cultivation is combined with the key points in this pulse-beating method, and the effect is better. First, the turbid gas in the body is discharged, and then the fresh light gas is collected for cooking, and the effect is naturally better. Believe it or not, follow the first process of internal qi cultivation and practice with the above methods for 10 days. This is a stepping stone to solar health care. If you practice 10 day in a row and 1 hour every day, you can open the door to solar health care. Verification standard: 1. After the elbow joint and knee joint are broken, the skin will not change color. 2. After the first process of cultivating internal qi, you can feel the warm or heavy feeling in your chest.
