Well-versed in both literature and martial arts, KO SING has been a retinue of Emperor KIN LUNG for many years. He helps LUNG to solve all kinds of problems, such as providing effective solution for the over-budget issue in cannon production. Since SING is such a genius, LUNG is jealous of him and never grants him an official title in the palace. Eunuch ON GOONG GOONG has selected some new maidservants for the palace and YUE YEE was chosen to work in the laundry. With the help of SING, LUNG is able to gain full control over the state and its policies. However, he is not able to choose the woman he truly want in the seraglio since the empress manipulates all the results of their “Turn the Tag” activities. LUNG is very upset about it and SING helps him to alter the Tags secretly. In this way, LADY SHUI, a blanked concubine at the seraglio, is able to serve the emperor eventually.
