Excuse me, what does "the beast returns to the cage" mean?

The meaning of the beast returning to the cage: the children at home are going to school. "God beast" refers to children. Affected by the epidemic, parents accompanied their children for many months. During this period, parents should not only be responsible for their children's food, clothing, housing and transportation, but also accompany their children to class and help them with their homework. Especially in the later period, many parents have already gone to work, but they have to be distracted to help their children with their studies.

As a result, countless parents are "desperate" and look forward to starting school as soon as possible, so there is a saying that the beast is returning to the pool.

God beast:

God beast refers to the creatures in ancient Chinese folk myths and legends, represented by two instruments and two saints (the sun and the moon shine) and four spirits (Qinglong, White Tiger, Suzaku and Xuanwu), which can be seen in Chinese classics.

Most of these creatures can't find entities in reality, but the composition of their images comes from reality. China used some ancient gods and beasts in divination, especially Daoism and Liu Yi. These beasts often appear in traditional buildings, playing the role of eliminating disasters, avoiding disasters and blessing.
