Extended data:

Meng Chun is the first month of spring. The lunar year is divided into twelve months: Meng Chun, Midspring, Ji Chun, Xia Meng, Midsummer, Late Summer, Qiu Meng, Midautumn, Qiu Ji, Mengdong, Midwinter and Jidong.

Summer is divided into Xia Meng, midsummer and the last month of summer. Xia Meng means to be alive, to begin to sprout. Midsummer means everything. In midsummer, "everything goes well"; When I reached the last month of summer, plants and trees were flourishing, and then I was facing decline. It was autumn.

Autumn can be divided into three stages: early autumn, mid-autumn and late autumn. There are six solar terms in autumn, namely beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew and First Frost.

In autumn, the most obvious change of natural landscape is in trees. The city will begin to clean up a lot of fallen leaves, and many tourists will flock to the mountains to watch the red leaves. Autumn, the third season of the year, is a transitional season from summer to winter. The lunar calendar is from beginning of autumn in July to beginning of winter in September, the solar calendar is from 9: 00 to 1 1, and the astronomical vernal equinox starts from the winter solstice.

The standard for meteorologists to study phenology is: after the intense summer heat, the average temperature for five days is stable below 22 degrees, which means that it is autumn, and it is over when it is below 10 degrees.

Winter includes beginning of winter, light snow, heavy snow, winter solstice, slight cold and severe cold. The time in beginning of winter and beginning of winter is about 1 1.7 on the Gregorian calendar. Beginning of winter can literally interpret Xinjiang as "the beginning, the beginning, the winter and the end, and the collection of all things." Folk customs regard this day as the beginning of winter.

Winter, as the end, refers to the end of field work for one year and the collection of crops after harvest. As the saying goes, "It's sunny in beginning of winter and cold in winter" and "It's cloudy in beginning of winter and warm in winter", the ancients observed the weather in beginning of winter and predicted the changes of winter temperature.
