For example, Yang's health-preserving ideas in Sunday Classic are "calming deficiency, following the true qi", "breathing essence, nourishing the mind independently" and "nourishing the mind in quietness, preserving the body shape and self-righting", which are mainly based on Huangdi Neijing and Huangdi Waijing, to cultivate sufficient true qi, unblock the twelve meridians and Eight Wonders Classic, nourish the internal organs and make them work normally. "Lingshu Jing" says, "Meridians are indispensable because they can decide life and death, deal with all diseases and regulate deficiency and excess." If the twelve meridians is compared to a big river, then the odd meridian and eight veins can be compared to a lake. The rise and fall of the true qi in the twelve meridians depends on the eight strange meridians, of which Ren Du is the most important. Ren meridian, which belongs to the Yin in the front and middle, always leads to a Yin meridian. Du meridian, which belongs to the Yang in the middle of the back, is the Yang meridian of the president. In Gong Jing's practice on Sunday, every meridian of the whole body will be unblocked once and for all, and there will be a leap in physical fitness.
I wish you persistence and success!
