I'm a person who loves reading novels, so I can't provide fictional palaces and concubines. However, in real life, the hierarchy in the palace culture varied according to the country, region, historical background and other factors. The palace hierarchy of different dynasties and countries was also different. The following are some of the hierarchy systems that may have existed in ancient Chinese courts: Queen: The highest ranking woman in the palace usually has a noble status and treatment. 2. Imperial Concubine: The palace women who were one level lower than the Empress usually held some more important positions such as Zhaoyi, Zhaoyuan, Shufei, etc. 3. Concubines: According to the palace hierarchy, the ranks of concubines vary according to factors such as gender, age, beauty, etc. Among them, Zhaoyi and Zhaoyuan are relatively low-level concubines. 4. Zhaojun and Lady Zhao: A special rank among the concubines is usually used to commend their beauty, talent, and loyalty. 5. Noble Concubines: Palace women whose status was second only to the Empress usually held some relatively light positions such as Zhao Nu, Lady, etc. 6. Always present: Women of lower status in the palace usually do not have special status and treatment. The above are just some of the hierarchy systems that may have existed in ancient Chinese courts. The specific hierarchy system varies according to the era, region, historical background, and other factors. In addition, some concepts in the palace culture, such as "palace fighting", may exist in fictional novels or online articles, which are different from the palace culture in real life.
