The Autumnal Equinox has arrived. The wind blows and cicadas chirp. | At the time when summer transitions to autumn, this brings a gentle care for your skin~ 

The Autumnal Equinox is the thirteenth of the twenty-four solar terms and marks the beginning of autumn. "Li" means starting, while "qiu" symbolizes the ripening of grains. As the four seasons progress in a sequential manner, the Autumnal Equinox is a crucial point when the yang energy begins to wane and the yin energy begins to grow. All things bid farewell to the vigorous growth of summer and gradually move towards refinement and maturity. The prelude to harvest thus slowly unfolds. 

As the season progresses into the beginning of autumn, the heat does not suddenly dissipate. As an old saying goes, "The heat is most intense during the three hottest days of the year," and there is also "One more heat wave after autumn." Even after the start of autumn, one still has to contend with the dry heat brought by the "autumn tiger." The daytime temperature remains high, and only at dawn and dusk does a gentle breeze occasionally touch the face. The task of preventing heatstroke cannot be relaxed. The temperature difference between day and night is gradually widening, the air humidity is gradually decreasing, and the dryness gradually spreads. This is what people often refer to as "autumn dryness." As the seasons change, nature needs to be balanced, and our bodies and minds also need to follow the natural rhythm and adjust our states appropriately. 

The ancients divided the Autumnal Equinox into three periods: "The first period: Cool wind arrives; the second period: Dew forms; the third period: Crows chirp in coldness."

The first period: Cool wind arrives

This means that after the Autumnal Equinox, the wind becomes cooler compared to that in summer, and it is different from the hot wind in summer.

The second period: Dew forms

Then, fog appears on the ground in the morning.

The third period: Crows chirp in coldness

And the cold-calling cranes also start chirping in autumn. 

Since ancient times, the ancestors adapted to the seasons and developed many lively and down-to-earth autumn-related customs. The custom of "chewing autumn" has been passed down for a long time. On the day of the Autumnal Equinox, people would chew on watermelons and other fruits, symbolizing getting rid of the scorching heat and waiting for the cool autumn. There is also the tradition of "building up autumn strength", where people have a reduced appetite in the hot summer and replenish their bodies moderately when the autumn breeze arrives, to make up for the losses during the summer. In ancient times, there were also folk customs such as welcoming autumn and drying autumn crops. People showed reverence for the seasons through simple rituals and hoped for a bountiful harvest of grains. These customs passed down from generation to generation embody the romantic spirit of the Chinese people in adapting to the natural order and loving life. They remind us to calmly perceive the changes in nature and take care of our bodies during the seasonal transitions. 

In accordance with the seasonal changes, maintaining good health mainly relies on the concept of "moisturizing". In daily diet, one can opt for foods like pears, lotus roots, and silver ears that are known for their moisturizing properties. Avoid consuming raw, cold, and spicy foods. Try to go to bed early and get up early to relax your mind and calm your emotions, and avoid worrying which may harm the lungs. The body needs nourishment internally, and the skin externally also needs to withstand the tests brought by autumn dryness.
