What are the rules of the ancient emperor's sexual life?

Abstract: The emperors of past dynasties also used the method of rolling dice. Whoever rolls the dice will serve the bed. The dice are called "angle-filing matchmaker". Tang Jingzong, who was in office for only three years, also invented a romantic arrow, which used bamboo skin as a bow and paper as incense as an arrow. Tang Jingzong let beautiful women stand in one place. He bows and shoots arrows himself. The shooter was infected by a strong fragrance and couldn't sleep at night. At that time, there was a saying in the palace: "Everyone wants to be in the arrow." According to the Han Dynasty's Chunqiu Biography, "Yin is confused by illness, and the heart disease is clear, so as to break the six qi. So it's not the beginning of the month, but the birth of the month. His ninth wife is married, nine are imperial, and eighty-one are kuya. Twenty-seven women for three nights, nine women for kuya, and three women for one night are fourteen nights. After one night, it is fifteen nights. Tomorrow will be the 15th, the 16th, and the next month will be less and less. The emperor's royal, and then five days. Also from the bottom up, gradually as for sheng, but also the meaning of the bright moon. Its royal is from the nephew, not the royal. Each nephew has six people for three nights, two people for one night, and four nights apart. My wife's exclusive night is five nights, so she went for five days, and on the sixth day she followed my wife, such as the latter method. ..... Anyone who is under the ninth wife and above the female royal family, but under 50, will be admitted to the royal family and stop at 50. After the wife is not involved in this case, fifty is still a royal family. Therefore, Neize said, "If my concubine is under 50 years old, she will be subject to the imperial rule for five days. You will know that fifty concubines will not enter the imperial palace. "This record means that there are 12 1 people in the harem, and there are countless maids. The emperor has the right to have sex with all harem women, but he is obliged to have sex with this 12 1 person regularly. According to Cui Lingen, it is not easy for the emperor to complete the prescribed tasks. Eighty-one wives are divided into kuya, with nine people every night. Do nine people go to the Forbidden City together, or take turns or draw lots to decide the dormitory? There is no clear statement. Twenty-seven wives are also nine every night, divided into three days; Nine wives are enjoying a day; The third lady also enjoyed the day. In addition, other concubines can't enter the palace after 50 unless they reach the level of queen and wife.
