 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.
