Standing piles can generally cure some chronic diseases, such as hypertension, diabetes, rheumatism and so on. Standing piles are really amazing. I have practiced martial arts before, but I don't know how to stand a stake. Later, I read a book, learned Qigong from a big brother, and slowly began to get used to standing piles. When it's time to learn Xingyiquan, it's also a standing pile at first. This feeling is great. After a long time, I feel rooted at my feet, full of energy and inexhaustible every day. Besides, my hearing is also very sensitive. If a sudden sound breaks the peace in an environment, my ears will move unconsciously. You can look at the story of Sun Lutang's apprentice Qi Gongbo, which is very good.
