It refers to the beautiful things in the world other than learning. It comes from teacher Zhou Heng from the School of Liberal Arts of Jiangsu University. He said to his students: "I will give you two opportunities to skip class. There must be something more important than class. It may be the Jianjia outside the building, or it may be the moon tonight." ."

Most interpretations on the Internet believe that Jian Jia comes from "Jian Jia". The Book of Songs "Jian Jia" mentions: The so-called beauty is on the side of the water. The moon comes from the meme "The moon is so beautiful tonight" (meaning: I love you), which is used to refer to love. But some people think that it just refers to some beautiful and meaningful things.

Introduction to "Jianjia":

Jianjia is green, and the white dew is like frost. The so-called beauty is on the water side. If you follow it back, the road will be long and blocked. Traveling back from it, Wan is in the middle of the water.

The leaves are luxuriant, and the white dew is still shining. The so-called beauty is on the water. If you follow it back, the road will be blocked and you will be able to advance. If you travel back from it, you will feel like you are swimming in the water.

The jianjia is collected, and the white dew has not stopped. The so-called beauty is in the river of water. Follow it back, but the road is blocked and to the right. If you go back and swim from it, you will be swimming in the water.
