You were kidnapped while walking around the city and sold to the imperial court. At first you were a washerwoman, and later you were taken in as the personal maid and taster of a concubine named Gyokuyo, because you knew herbs well and saved her and the emperor's daughter.
One day the emperor decided to have a feast where everyone was present: concubines, their maids, officials, advisors, the army, and even a few people from other countries.
before the holiday, other services of Concubine Gyokuyo did your makeup and dressed you up nicely. When you were walking with the maids, Jinshi approached you and gave you a hairpin
after a few hours you were gathered on a large stage where you and 3 other tasters had to taste the food and then give it to the concubines
