If there is no iron ore, you can use mung beans instead. Iron sand palm is a common method of hard qigong, and each sect has its own unique practice method. I'll introduce you to a scientific, safe and effective method. 1. Sew a pocket and put mung beans in it. 2. Shake hands before work, that is, the two arms move up and down naturally in parallel until 100 times. 3. Beat the sandbag. Place the sandbag parallel to the navel. Hands are too overhead and naturally fall from top to bottom. Flap in turn. Pat the back of your hand with one hand, then clap your hands, and then change the other hand. It is appropriate to start with 5 minutes, and it can be extended to 20 minutes with the growth of skills. 4. Soak your hands with medicine and warm water after slapping. Prescription: Isatis indigotica, Caulis et Folium Gaultheriae Yunnanensis, Cortex Lycii, Herba Violae and Herba Taraxaci. Soak the medicine in boiling water for 5 minutes, and then soak your hands. Note: it is best to practice from 7: 00 to 9: 00 every night, because at this time, according to the running order of human meridians, it happens to be the pericardium meridian, while the previous hour is the kidney meridian, yin deficiency. At this time, the kidney meridian is full of essence, which is beneficial to exercise. Chinese medicine says that "the kidney governs the bone and produces marrow", that is to say, your bones and muscles will be strong if you have enough kidney qi, so the kidney meridian is full of essence from five to seven, which is just suitable for your follow-up: you need so many Chinese medicines. . . There is no Chinese medicine for sale in our town. . There are only western medicines in the drugstore. . . . . . Can you use something ordinary instead? Answer: If it's not important, you can buy some western medicine ointment, such as voltarin or Yunnan Baiyao aerosol.
