Is beginning of autumn the same as the autumn solstice?

Beginning of autumn is different from the solstice in autumn. Beginning of autumn and autumn solstice belong to one of the 24 solar terms, but they are two completely different solar terms. Beginning of autumn is the first solar term and the starting point of autumn. However, beginning of autumn does not mean that the hot weather is over, and beginning of autumn is still in the heat period and has not yet come out. The solstice in autumn refers to the autumnal equinox. On the autumnal equinox, the sun is located at 0/80 degrees of the yellow meridian/kloc, and the sun is almost direct to the equator, and day and night are equal again. After this day, the days in the northern hemisphere get shorter and the nights get longer. From autumn to the future, the weather will be much colder than after beginning of autumn, which is the strongest time in autumn.
