The official prescription "Taiping Sheng Huifang" in Song Dynasty has both theoretical explanation and achievement explanation. The General Record of the Holy Relics puts forward the idea of "governing the gods" and advocates the application of guidance and persuasion. Su Shen and Liang Fang advocated practicing the method of regulating qi, believing that to succeed, we must persevere. The book "Providing for the Aged and Serving the Family" uses six-character qi prescription to prevent and treat senile diseases, which is widely adopted by later generations.
Doctors in the Jin and Yuan Dynasties also used Qigong to keep fit, and many of them played a role. Liu said, "People eat, drink and adjust their body shape, and people are alive to adjust their spirits." He thought that "closing their eyes in the middle of the night and sitting in a movie" could "boost their vitality" and advocated "regulating their breath and restoring their spirits."
