In "The Romance of the West Chamber", what is the name of the girl next to Cui Yingying?

Yingying’s personal maid is called Matchmaker

The character Matchmaker became famous in "The Romance of the West Chamber" written by Wang Shifu of the Yuan Dynasty. After the Northern Song Dynasty, this story was widely circulated until the Southern Song Dynasty, when it was adapted by folk artists into the story "The Story of Yingying" and the official version of the drama "Yingying Liuyao". Dong Jieyuan of the Jin Dynasty further adapted this story into "The Romance of the West Chamber". Wang Shifu's "The Romance of the West Chamber" is a re-creation of the story of Cui and Zhang that has been circulated in history, especially "The Romance of the Western Chamber". The character of Matchmaker appears as a maid in the stories of Cui and Zhang. Although she has a name in Yuan Zhen's "The Story of Yingying", she is not very important. She is an ordinary maid. It was spread from the Tang Dynasty to the Song Dynasty. Her status has remained the same throughout the process. Starting from "Dong Xixiang", this image was successfully created and turned into a flesh-and-blood artistic image.
