The beginning of four ancient poems in autumn

"Autumn Night" Don Tu Mu. In the autumn night, candlelight reflected the screen, and Fan slapped the fireflies with his hand. Day and night are as cool as water. Sit and watch the morning glory and Vega.

Beginning of autumn is the 13 of the 24 solar terms, and the first solar term in autumn usually falls on August 7th or 8th of the Gregorian calendar every year.

The change of the whole nature is a step-by-step process, and beginning of autumn is a turning point in which the Yang gradually closes, the Yin gradually grows, and the Yang gradually gets cloudy.

In nature, everything begins to grow from lush to mature. Beginning of autumn doesn't mean the extreme hot weather is over. Beginning of autumn is still in the summer heat period, and the summer heat will not come out until the second solar term in autumn. It's still very hot in early autumn.

The so-called "heat is in three volts", and some people say that "it will fall after autumn". After beginning of autumn, there will be at least one volt of extremely hot weather.

According to the calculation method of "dog days", the days of "beginning of autumn" are often in the middle of dog days, that is to say, the heat is not over, and the real coolness usually comes after the Millennium solar terms. The watershed of summer heat is not in the solar terms in beginning of autumn.
