The years are suddenly getting late, and it is already autumn in a blink of an eye.
The change of seasons is always so silent. Inadvertently, everything in the mountains and rivers has secretly changed its appearance.
Autumn has arrived when the first leaves slowly fall with the wind. With a hint of calmness and a touch of coolness, it quietly hit my heart.
It is like the return of an old friend, making people happy.
At this time, the autumn colors are still light. The lush green has not faded yet. The yellow color of the chrysanthemum is still brewing. The red of the maple leaves has not yet faded. The coldness and desolation are still on the road in the distance.
Autumn
Autumn is one of the four seasons of "spring, summer, autumn and winter". In our country, the "beginning of autumn" of the 24 solar terms is traditionally used as the starting point of autumn. Entering autumn means that rainfall, humidity, etc. tend to decrease or decrease, and everything in nature begins to grow from lush growth to bleak and mature.
The four seasons are divided according to the climatic average temperature of modern scholar Zhang Baokun. The indicator is that the period when the average temperature is lower than 10℃ is winter, the period when the average temperature is higher than 22℃ is summer, and the period between 10 and 22℃ is spring and autumn respectively. .
