What does it mean to wait for a cool breeze, a white dew and three chills?

"Cool breeze, dew, cicada singing" means that after beginning of autumn, the wind at this time is different from the hot wind in summer, and there will be fog on the ground in the morning and cicada singing will begin. The so-called "three weathers" exist in every solar term. Every five days is a waiting period, and the third waiting period is 15 days, which is exactly the number of days in a solar term, and the date between waiting and waiting is postponed.

The cool breeze in early autumn shows that the wind has cooled after beginning of autumn, especially in the evening when autumn is getting stronger.

The sound of egrets after beginning of autumn II shows that the weather is getting colder and colder at this time. In the morning, because of the large temperature difference between day and night, there will be white fog in the morning, all of which are fog.

The cicada singing in beginning of autumn shows that there is cicada singing at this time, but it is not cicada singing in Xia Chan, but cicada singing in Xia Chan, because the weather is hot, and the hotter it is, the stronger it is. The cold here is Qiu Chan. This Qiu Chan calls it because it is cool.
