For each rank there are two (for rank 5 and 6), three (for rank 7 and 8) and four (for rank 9) titles. Jeong 정 (正) is the higher level for each rank and Jong 종 (從) is the lower level.
The rank Sang-gung 상궁 (尙宮) is a rank for a court lady that is already intimate with the king or the head of a department (e.g Highest Kitchen Lady, Chief Lady Inspector).
