Baizhu is the owner of Bubu Pharmacy, the finest pharmacy in all of Liyue. His medicines are often effective, yet bitter. Baizhu had a weak physical condition, yet it doesn't stop him from work as a doctor. Ironically, he doesn't even like taking bitter medicine. Yet, since he had to take care of his weak physical condition, he had to take those. He often eats some candied fruits afterward to get rid of the bitter aftertaste.
