The crown prince or the little emperor began to receive sexual enlightenment education before entering adolescence. The eunuch is responsible for the sexual enlightenment of the emperor (prince). There are a large number of erotic palace pictures in the palace, and a hall is specially set up, which contains murals and statues showing sexual intercourse, and the eunuch is responsible for opening the doors of the temple.

"Wan Ye Li Supplement" records that there is a happy Buddha in the palace of the Ming Dynasty, which is said to be a foreign tribute and left over from the Yuan Dynasty. "The makeup of the two Buddhas is strict, deadlocked, consistent and maneuverable." Before the emperor's wedding, the eunuch invited the emperor to enter this temple and bowed first. After the worship, "let him touch the hidden place and silently understand the method of handover." It seems to show them pornographic pictures. ........................................................................................................................................................................
