Traditional Chinese medicine health care emphasizes that "the four seasons are suitable for cold and summer, harmonious with emotions, and soft and hard"; Traditional Chinese medicine (TCM) adheres to the advanced concept of "preventing diseases" in Huangdi Neijing, and has always emphasized the way of health preservation and that no disease is the best. Huangdi Neijing holds that all diseases are caused by imbalance of yin and yang and lack of healthy qi. The key to health preservation lies in regulating the balance of yin and yang, strengthening the body resistance, stimulating healthy qi, and making all diseases heal themselves and live a long and healthy life.

Through three levels of practice, we have both form and spirit, from the achievement of "doing something" to the realm of "forgetting things and doing nothing"
