Why are the fallen leaves in autumn so charming?

I like the fallen leaves in autumn best, because golden yellow is beautiful.

Autumn is the harvest season, and many plants mature in autumn. In autumn, in nature, the qi of yin and yang begins to change, the yang is gradually declining, the yin is gradually flourishing, the climate turns from hot to cold, and everything is born with cold and gradually declines. This is the season of alternating hot and cold. As the temperature gradually drops, the leaves of many deciduous perennial plants will gradually change color, wither and fall off, leaving only branches for winter.

Panicum miliaceum will come to the end of his life, wither and die. Seasonal variation covers many aspects of climate characteristics, and it is not accurate to judge autumn only by temperature. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow, and the leaves begin to fall and the crops begin to mature.

Extended data

In China, traditionally, "beginning of autumn" in the 24 solar terms is taken as the starting point of autumn. Entering autumn means that rainfall and storms tend to decrease or decrease, and everything in nature begins to mature from lush.

At present, the four seasons are often divided according to the temperature change, and the division of "climate average temperature" by modern scholar Zhang Baokun is adopted. According to the weather average temperature method, the daily average temperature for five consecutive days is between 10℃-22℃. Entering autumn means that the hot weather has passed and it is beginning to cool down.
