I am Liu Yulin, a Taoist doctor from Qichun in 1988. I live in a mountain valley with my son Guoguo. There is no hustle and bustle of the city here, only the fragrance of Qi moxa, the fireworks of the neighborhood, and real medical cases prepared using ancient moxibustion and massage. There is no golden finger in the system, only the craftsmanship passed down from my ancestors and a heart that wants to live a good life. In this mountain wilderness, I heal others while my son and I grow up slowly.
