What is the whole poem about dressing indiscriminately in February and August?

Dressing in disorder in February and August, the whole poem is as follows:

Autumn is coming, throw away the fan.

In February and August, I dressed indiscriminately.

There is little summer rain and early autumn frost.

In August, the wild goose gate opens and its feet are frosty.

One autumn rain and one cold, ten autumn rains need to wear cotton.

It is warm in August, warm in September and sunny in October.

Analysis of the phenomenon of disorderly dressing in February and August

In February and August, casual wear mostly occurs in February and August of the lunar calendar, which corresponds to March and September of the solar calendar in most years. Usually in March, the warm air mass begins to counterattack, and the influence of cold air is weakened. The maximum temperature rises rapidly during the day, while the minimum temperature rises slowly at night, and the temperature difference between day and night is very large. Occasionally, the cold air will stubbornly resist, the temperature fluctuates greatly, and everything is worn this season.

In Shanxi, Shaanxi, Gansu, Tibet, Xinjiang and other places, the temperature rises rapidly during the day, as if a day passes through winter and spring, and the clothes are "chaotic"; In Beijing, Tianjin, Henan, Shandong, Anhui, Jiangsu, Hunan, Hubei and other places, the temperature difference between day and night reaches 15℃, the weather is hot and cold, and dressing is "chaotic"; However, the temperature difference between day and night in the northeast and south is very small, so there is no trouble of "disorderly dressing".
