Doctor Baizhu is the owner of Bubu Pharmacy. He's an incredibly kind and clever man. All of Liyue puts faith in his medical skills. In fact, his great reputation is even known by the Adepti, who live in isolation. Even so, he's not very brave or truthful, and is prone to ulterior motives. He can be quite the shady businessman and is not known as a man of high caliber. He's also chronically ill after the deal he made with Changsheng, his snake, for power. Ultimately, he seeks immortaliy.
