Meaning: Zhang Daozhong's note: "One, stop, Master, the moon, what is right is true, and everything is positive. The master also noticed that the moon is green, and green is the color of the east, the first of the five parties, and the beginning of the four clean-ups People who can really do evil songs are also the foundation of immortals. " The meaning of Zhang Daozhong's explanation is still obscure. According to the composition and meaning of this word, it is opposite to the word (Tibao) in the upper part. The word "Shenbao" in the first part of the couplet is "Zhengqing", which clearly shows that people know that there are three treasures in the body, namely essence, qi and spirit, and they should stick to it and not lose it. It means that the laity is pure and pure, which is the foundation of Xiu De. Therefore, it has the opposite meaning of Tao and virtue inside and outside.

"Green", in the five elements of wood, wood is blue, in the four seasons for spring, in the four directions for the east, belonging to the angry side of everything. Spring is the first year of life. Plants should be born in spring, with lush foliage, which means that people can be full of vitality as long as they keep healthy, just like plants meet spring.

It can be seen that the word "Zhengqing" embodies the meaning of being selfless and not doing evil in practice, and is full of commercial flavor.
