Four seasons in a day: there are four seasons in a year and four seasons in a day. A day's spring is a sunny spring, and three in the morning is the beginning of a day's spring; Summer is from 9 am to 3 pm; From three o'clock in the afternoon to nine o'clock in the evening, it belongs to the autumn of a day, which is the autumn of a day; From 9: 00 p.m. to 3: 00 a.m., it is a winter day, that is, a winter day.
Of course, this may not be everyone's view. If I divide it into 24 hours a day and 6 hours a season, among them, spring corresponds to 5 am 1 1 am, summer corresponds to noon 12 to 5 pm, and autumn corresponds to 6 pm 1 1 pm.
Although it will get dark at 8 o'clock in the evening, it should be considered as winter, but now the living habits, evening is the best time, drinking, singing and dancing square dance. The real winter should be 1 1 o'clock in the evening and 5 o'clock in the morning.
