Wu Tong village fortune-telling

Pure personal opinion, no offense, please don't mind if you are wrong.

This sign briefly describes the end of July, the beginning of August and the fifteenth day of August in the lunar calendar. Indus leaves refer to the arrival of autumn, and the following three paragraphs should be explained together:

Passer-by is the third person, referring to passers-by who are away from home. When a guest goes home, he means the way home, and when he goes, he means he is in a hurry.

The emperor here refers not to the emperor, but to the Duke of Zhou. Validity is a homophonic word (calendar), validity refers to time, and downwind refers to autumn wind.

Carrying all the sounds (sides), here's carrying refers not to riding, but to home. The bright moon in the sky does not mean missing time, but refers to the full moon in the Mid-Autumn Festival in August.

Connection: The leaves of the buttonwood tree fell to welcome the arrival of August, and everyone who went out hurried home after finishing their work. Thanks to Duke Zhou for coming at the right time, the autumn wind blew, and passers-by spent a reunion night at home, leaving only a full moon hanging high in the sky.

It mainly means that the author misses time, being alone in the Mid-Autumn Festival, for the company of autumn wind and bright moon.
