What are the taboos on the day before the summer solstice?

There are no taboos before the summer solstice. Because the summer solstice is only a solar term, it is a hot time. High temperature, high humidity and occasional thunderstorms are the weather characteristics from summer to the future.

The summer solstice is in midsummer, that is, at noon, belonging to the sun; Although summer is full of yang and the daytime is the longest, it is not necessarily the hottest day of the year, so the heat near the surface is still accumulating and has not reached the maximum. The summer solstice is not only one of the 24 solar terms, but also a festival in the ancient "four seasons and eight festivals". Since ancient times, people have the custom of worshipping gods and ancestors in the summer solstice.

After the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the days in the northern hemisphere began to shorten gradually, but the temperature will continue to rise for a while, because the heat radiated by the sun to the ground is still more than the heat radiated from the ground to the air, so there is a saying that the summer solstice is not too hot. As the saying goes, "it's a hot day in dog days", and the real hot day is from mid-July to mid-August on the Gregorian calendar.
