Different from other generations, concubines in the Qing dynasty were no longer visited by the emperor himself. The Qing emperor had his own system. Every day at dinner, decide which concubine will serve the bed that night. Every concubine has a green card with her name on it. When preparing meals, eunuchs in the worship room put a dozen or dozens of green-headed cards in a big silver plate, which is called a meal card. When the emperor finished eating, the eunuch raised his plate and knelt before the emperor. If the emperor is not in the mood, just say "go". If you are interested, just pick a card, buckle it and the back will get up. The eunuch took this card and gave it to another eunuch, who was responsible for carrying the concubine who asked for happiness into the emperor's bedroom. Due to the high vigilance of the Qing emperor, in order to prevent assassins from appearing in the concubines, the concubines had to come to the emperor's bedroom naked. The method is to take the concubine to a room not far from the emperor's bedroom and take off her clothes. The eunuch wrapped her in a red brocade quilt or coat, shouldered her and took her back to the emperor's bedroom. Before you go to the sofa, take off the red brocade quilt or coat wrapped around it. What happened later was recorded by people at that time. "At that time, the emperor would lie down first and be stopped." The princess climbed barefoot and made friends with the emperor. The steward of the worship room and the eunuch of the camel princess stood outside the window. If the time is too long, the flight attendant will sing: Time is up. If the emperor should not, then sing it again, and so on. This is the fate of the emperor. The princess was dragged out from the emperor's feet. The camel princess is still wrapped in a camel, and the camel is gone. After going, the general manager will kneel and plead: Will you stay or not? The emperor said: Don't stay. Then gently press the acupoint from the supervisor to the concubine's back, and the dragon essence will flow out. Say: stay. Then the manual of the pen says: On a certain day, the emperor was very lucky for a princess. Therefore, pregnancy preparation is also necessary. So is the ancestral customization of this palace. "
