Why did a good girl in ancient times bring a maid when she got married?

When ancient ladies got married, the maid was their personal maid, responsible for taking care of their daily life and emotional needs. Escort maids are usually sold to their homes at an early age. After long-term cultivation, they have mastered some skills of caring for people and have a close relationship with young ladies. Therefore, when choosing escort maids, they will have a little more advantage than ordinary maids.
