1. "Poetry of the Twenty-Four Qi: Mid-February at the Vernal Equinox" Tang Dynasty·Yuan Zhen

Don't let the two Qi compete with each other, and the rain will flow at the Spring Equinox.

Watch a movie in the rain, listen to the thunder when the clouds pass.

The mountains are green and the sky is green, and the forest flowers are facing the bright sun.

The birds in Liangjian are talking, and desire seems to understand human feelings.

2. "Drunken Taoyuan·Nanyuan during the spring outing" Five Dynasties·Feng Yansi

During the spring outing in Nanyuan, the wind was gentle and the horses neighed.

Green plums are like beans and willows are like eyebrows, and butterflies fly as the day goes by.

The dew is heavy, the grass smoke is low, and people’s curtains hang down.

On the swing, I untie my sleepy clothes, and the two swallows return to the painting hall.

The Vernal Equinox is one of the twenty-four solar terms and the fourth solar term in spring. Douzhimao, the sun's yellow longitude reaches 0°, and the festival occurs on March 19-22 of the Gregorian calendar every year. The vernal equinox is of great significance in astronomy. On the day of the vernal equinox, the sun shines directly on the equator, and day and night are equinoxed in the northern and southern hemispheres. From this day on, the direct position of the sun continues to move from the equator to the northern hemisphere. The days begin to be longer than the nights in the northern hemisphere, and the opposite is true in the southern hemisphere. In terms of climate, there are also relatively obvious characteristics. After the vernal equinox, China has entered a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of North China.
