Harmony is a set of health and fitness techniques handed down by Confucius. It is not qigong and martial arts, but a set of healthy behaviors. "Harmonious work" achieves a harmonious and natural state by regulating people's physical, psychological and social behaviors, and learners achieve the purpose of preserving health and treating diseases through long-term unremitting efforts. In recent years, a large number of practices have found that the effect of Hegong on controlling cancer recurrence and metastasis is very significant, so it is also called Hegong Anti-cancer Function.

He Hegong inherited the essence of the Chinese nation's "harmony" thought. Explain the principle of life and disease with "harmony", and think that "harmony" is the best state of life activities, "harmony" loss is the root of disease, and seeking "harmony" is the highest realm of treating diseases and keeping in good health.

Harmony is divided into six chapters, each of which is complete and independent. It is suitable for all people who pursue health and love health to learn.
