Autumn has the same meaning." "Spring and Autumn Fanlu·Yin Yang Chu Ru Upper and Lower Chapters" says: "The spring equinox is when yin and yang are half and half, so the day and night are equal and the cold and heat are balanced." The Spring Equinox is also a festival and sacrificial celebration. Ancient emperors had the ritual of worshiping the sun in spring and the moon in autumn. The Emperor of Zhou Dynasty offered sacrifices to the Sun at the Sun Altar. "Book of Rites": "Sacrifice the sun on the altar." Kong Yingda's commentary: "It refers to the vernal equinox." Pan Rongbi of the Qing Dynasty wrote in The Chronicles of the Capital: “Sacrifices to the sun on the Spring Equinox and to the moon on the Autumn Equinox are grand national ceremonies, and scholars and common people are not allowed to offer sacrifices on their own. On the day of the vernal equinox, the sun shines almost directly on the equator, and the day and night are almost equal in most parts of the world. However, near the North Pole (90° north latitude) and the South Pole (90° south latitude), a special phenomenon can be observed where the sun circles on the horizon all day long. After the vernal equinox, the position of direct sunlight continues to move northward, and the days begin to become longer and the nights shorter in the Northern Hemisphere. The Spring Equinox is a relatively important solar term. It not only has astronomical significance: the day and night are equal in the northern and southern hemispheres, but also has obvious climatic characteristics. During the Spring Equinox, my country enters a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of North China. On the vast land, willows are green, warblers are flying, grass is growing, wheat is jointing, and rape flowers are fragrant. During the Spring Equinox, except for the high-altitude mountainous areas where it is winter all year round and the areas north of 45° north latitude, the average daily temperature in all parts of China rises steadily to above 0℃. At this time, the severe cold has passed and the temperature has risen rapidly, especially in North China and the Huanghuai Plain. The average daily temperature has risen to above 10℃ almost at the same time as the rainy areas along the Yangtze River in the south of the Yangtze River, ushering in the bright spring. During the Spring Equinox, the East Asian trough has significantly weakened, and the trough-ridge activity in the westerly belt has increased significantly. Low pressure activities and cyclone development are common from Mongolia to the Northeast. The movement of low pressure guides the cold air southward, and the northern region is prone to strong winds and sandstorms. When the long wave trough moves eastward, affected by the convergence of cold and warm air masses, continuous rain and late spring cold weather will occur.
