If you want to keep fit, you can usually practice an action that many foreigners are practicing and stick to the wall. Sticking to the wall, also known as squatting on the wall, was originally a secret recipe used by Neijia Boxing to loosen the waist, and was later spread by health scholars. People face the wall, nose and toes touch the wall, and then slowly squat down with their noses against the wall until their legs are completely bent, and then slowly get up. It helps to relax the waist, so it can be used as the basic skill of Neijia Boxing. It can not only strengthen the kidney, but also be a good way to keep fit. It can also strengthen the up-and-down opening and closing of human mixed gas and effectively correct the gas deviation in the body.
