Generally speaking, achieving the balance of yin and yang is based on the yin and yang of traditional Chinese medicine and achieved through certain methods. These technologies include: 1. TCM conditioning; 2. Physical exercise; 3. Qigong practice. These points are generally carried out at the same time, but there are primary and secondary points. Reversing the above order is its primary and secondary.
If you want to keep healthy by yin and yang, I suggest looking for a master instead of a famous teacher. That's all that matters. Otherwise, it is difficult to gain much.
