Baizhu, the owner of "Bubu Pharmacy," is a master of the medicinal arts. He is benevolent and kind, yet also shrouded in mystery and other contradictions. And though only a mortal, a talking snake with powerful spiritual energy is always wrapped around his shoulders. Baizhu's physical condition is extremely poor. Day after day, Baizhu heals his patients. His ever-present smile hides the numerous bitter medicines he takes and the pain he suffers alone.
