What are the phenological characteristics of Tomb-Sweeping Day?

The ancients in China divided Tomb-Sweeping Day's fifteen days into three periods: "When the tung flower first bloomed; The second vole becomes _; I'll see you when I wait for the rainbow. " That is to say, at this time, the white paulownia blooms first, then the happy voles disappear in the shade, and all return to the underground caves, and then the rainbow can be seen in the sky after the rain.

By Qingming, the average daily temperature in most parts of the country had risen to above 12℃, with fresh air and bright sunshine, except in the northeast and northwest regions. "It rains in succession during the Qingming Festival". In April, the rainy days in the south of the Yangtze River are mostly around 16 days, and the rainfall is above 100mm, with more rainfall in some areas, and abundant rainfall can meet the needs of crop growth. At this time, the temperature in South China has reached 15℃ and the rainfall continues to increase. But at this time, the north is prone to drought and little rain, and the north and northwest are prone to spring drought.

Qingming flower letter: first-class tung flower, second-class wheat flower, third-class willow flower. In ancient Qingming poems, tung flowers were often written. For example, Bai Juyi's poem "Tung Hua" says that "every day in spring, it will be clear and clear", and Bai Juyi's poem "Cold Food Riverside" says: "When I see Tung Hua suddenly, it will be clear the next day." This means that when I saw the red paulownia flowers, I realized that it was clear. The second representative of Tomb-Sweeping Day Qi is Maihua, the flower with the shortest life, which is called "light and fine" and "discerning". When Liu bloom falls in love with his family, people like to insert willows and eat willows in Qingming Festival. Scholars in ancient and modern times always chant willow flowers or fold willow leaves to express their reluctance.

Interpretation of the three-phase meaning of the twenty-four solar terms;

Wait: Tong Shihua

During the Qingming Festival, bloom is beautiful. In spring, everything recovers. In Tomb-Sweeping Day, the sun is more abundant, and all kinds of flowers are blooming.

In the eyes of the ancients, Bai Tong Bloom's life was a little later, just in the Qingming period, so it was regarded as a sign of the arrival of Tomb-Sweeping Day. Qingming, walking in nature, watching all kinds of flowers fade slowly, a place full of flowers, the instantaneous beauty is mud, which makes people sad. However, on another ramp, I suddenly saw a tall white paulownia tree standing in a small farmhouse under thin white clouds. The tree was full of purple and white bell-like flowers, full of fragrance in the leaves, which gave people a surprise and shock! This is the power of blooming, and it is also a touching part of life. No wonder the ancients had a soft spot for this kind of flower.

The second stage: voles become quails.

The vole hid back in the cave because of the strength of the sun, and the birds who love the sun began to come out and move.

The vole is the most yin thing, and the bird is the most yang thing. This means that the yin hides and the yang grows stronger. It can be seen that the sight of grass growing and warblers flying in spring conforms to the changes of nature.

Waiting for the third time: the first sight of the rainbow

It rains in Tomb-Sweeping Day, so there will be a rainbow.

In the beautiful spring, with the erosion of rain, the lush green leaves cover the bare soil and absorb the dust, beautiful rainbows can appear in the sky after the rain.
