The first and second floors of Mysterious Doctor Pavilion can both have sitting doctors, and there are many physicians. Only Li Xian wore a mask.
However, through communications, Yao Baishun and Yao Yin intended to assist, helping Li Xian conceal his traces and cover his appearance and name. Concurrently, due to the incident with Li Xian, Mysterious Doctor Pavilion indeed had physicians who were jealous, taking advantage of this opportunity to set new rules, ordering all sitting doctors to wear masks while practicing medicine. The physicians had no objections and wore masks for duty.
Thus, all the doctors wore masks, concealing their appearances. Li Xian had already changed his medical position, intending to disguise himself.
