They began to learn music in addition to medicine. When the successor King Jungjong ascended to the throne, "uinyeo" served as "uigi" (medical entertainer) at court officers' parties. After 1510, the fifth year of the King's reign, the government prohibited "uinyeo" from attending parties by law several times and forced them to go back to their original mission in medicine. In spite of this effort, the once strict morality was not rectified, and "uinyeo" still attended parties. At feasts, "uinyeo" who worked at "naeuiwon" (royal health clinic) wore a "garima" (a crown) made with black silk, while "gisaeng" wore a black "po" on their head. As "uinyeo" who belonged to "hyeminseo" (clinics for the public) were called ""yakbang gisaeng"" (entertainers of the medicine room) they were regarded the first rated entertainers over other female official entertainers assigned to government offices. Due to their lowborn origin, "uinyeo" did not gain the same social status as male doctors and barely retained their existence as a group of the lowest class of society.
