1, the imperial concubine is one level higher than the imperial concubine, second only to the queen. If there is no queen in the palace, the imperial concubine is the head of the Sixth Hospital.

2. After the establishment of the imperial concubine system in the Northern and Southern Dynasties, the imperial concubine was second only to the queen, and the harem title was higher than the wife. Until the Qing dynasty, the harem no longer had the title of lady.

3. During the Ming and Qing Dynasties, Ming Xianzong established the imperial concubine, which was above the imperial concubine and below the queen. Therefore, in the Ming and Qing dynasties, the imperial concubine was the only concubine who was higher than the imperial concubine. The imperial concubine of the Ming dynasty can have many people, and the imperial concubine of the Qing dynasty can only have one person.
