The Qing Chronicles

If you need any help understanding the ranks of the harem women,

Empress (Huanghou): (1)
- There can only be one empress, and she is the legitimate wife of the emperor. Highest ranked woman.

Imperial Noble Consort (HuangGuiFei): (1)
- This title is rarely given. It is usually only given to a woman before she is about to be empress, or essentially as a step empress. Also sometimes given to sickly noble consorts. 2nd highest ranked woman.

Noble Consort (GuiFei): (2)
- Title is given to senior women that advise the empress on matters of the harem. 3rd highest ranked woman.

Consort (Fei): (4)
- 4th highest ranked woman.

Imperial Concubine (Pin): (6)
- 5th highest ranked woman.

Noble Consort (GuiRen): (No Limit)
- 6th highest ranked woman.

1st Class Female Attendant (ChangZai): (No Limit)
-7th highest ranked woman.

2nd Class Female Attendant (DaYing): (No Limit)
-8th and lowest ranked woman.

Chosen Maid (GuanNvZi)
- Not an official rank. Given to maids that also sleep with the emporer.

Lady (NvShi)
- Not a rank. Given to women (imperial concubine and higher in status who own a manor) who are demoted to commoners. Assuming they are still the master of the palace, they will receive the title "Lady of (Palace name)"

Mistress
- Colloquial title given to commoners that sleep with the emperor. They most likely are then simply sent home with hush money. Other times they are forced to be nuns or executed to protect the emperors pristine image.

Next, harem of the prince:

Primary Consort (DiFuJin): (1)
- Main wife of the prince. If the prince becomes emperor, she becomes consort as she is the legitimate wife of the prince.

Secondary Consort (CeFuJin): (2)
- They often advise the Primary Consort on matters. If the prince becomes an emperor, they often are above the rank of imperial concubine.

Consort (GeGe): (No Limit)
- Not to be confused with the consort of the emperor. These are the lowest rank of women that sleep with the prince.

Mistress
- Random women.
