Chu Qiao Chuan: Why is Yu Wenyue called Chu Qiao Xing Er?

When Chu Qiao successfully became Yu Wenyue's maid, Yu Wenyue named her Xing 'er, which had two meanings. First, in a big house in ancient times, handmaiden and master could not have the same name, and Jing Yueer and Yu Wenyue had a homonym, which was one reason why Yu Wenyue changed her name, and another reason was that Xing 'er always revolved around the moon, and the moon shone to protect Xing 'er, which also indicated laterally.
