The owner of Bubu Pharmacy. Male Height: Approx. 185cm He carries a white snake named Changsheng around his neck. He is well-versed in medicine and is always deep in thought, though it is difficult for others to read his mind. Region/Affiliation: Liyue As the owner of Bubu Pharmacy, the medicines he formulates are exceptionally effective, but they are also said to be incredibly bitter. In addition to being a pharmacist, he is a highly skilled doctor. He occasionally travels to various parts of Liyue to make house calls upon request. While many patients are saved by his smiles and prescriptions, few know that his own physical condition is extremely poor. However, he never shows this to anyone except those closest to him to avoid causing anxiety to his patients, and even then, he does not speak of it. Due to his thin-framed glasses, drooping eyes, and polite speech, some travelers initially had a suspicious impression of him, similar to Kamisato Ayato, and Paimon felt the same way. He has fair skin and long green hair, with half of it tied up in a bun and secured with a distinctive hair ornament. He has golden, snake-like eyes, and his oval-framed glasses are eye-catching. He wears loose, Chinese-style clothing based on pale jade green and white. He carries items such as a gourd and medicine pouches around his waist. In truth, while he has a somewhat "mad scientist" side, he is introduced as a person with a sincere desire to save patients, dispelling personal concerns about his character. Although he is a doctor by trade, his hobby is formulating medicines. Due to his background of researching immortality while dealing with his own frail body, his tone becomes solemn when speaking about the "weight of life" or "consequences." He is very polite and kind to his patients, healing many illnesses with unconventional methods and high skill. He is beloved by children and deeply trusted as a medical professional by the citizens of Liyue. His hidden side is one of unfathomable thoughtfulness; he is always deep in thought, and it is difficult for others to discern what he is thinking. It is suggested that behind his aloof attitude, he hides a significant purpose or secret. A white snake is coiled around his neck, and they share a buddy-like relationship, sometimes engaging in conversation. Furthermore, Changsheng is not just a talking snake. She is an ancient illuminated beast with the supernatural power to "transfer vitality and illness." In her weakened state, she cannot survive without contracting with someone and sharing their vitality. The conditions for a contractor are to be human, to be sincere, and to be a relative of the previous contractor. Therefore, this lineage of medical practitioners, from the first generation to Baizhu's master, has burned through their own sincerity and taken on illnesses, scattering their own lives in exchange for saving many others. First person: I (Watashi - polite/soft) Second person: You / Guest-san Tone: Polite and soft way of speaking. "...is it?" "...I see." "...you know."
