The “24 Solar Terms” is the product of ancient Chinese farming civilization. It is a system formed by ancient ancestors, that follow agricultural seasons, by observing the movement of celestial bodies in order to understand the changing laws of seasons, climate, phenology, all in the cycle of one year. According to the arrangement of the 24 solar terms, Li Chun, or the beginning of spring, is the first solar term, during which you can see a slight green color. In the eyes of the ancients, the Wuhou, or natural wonders, of Li Xia are : “The Eastern Wind Thaws the Ice”, “The Rumbling of the Pollinating Insects”and “The Fish Breaks Through the Ice.” In Spring days, the east wind arrives bringing warmth and the earth begins to thaw. Five days later, the pollinating insects slowly wake from their deep sleep.Another five days later, the ice in the river begins to melt, and the fish start to swim to the surface of the water. At this time, there are small broken pieces of ice on the water’s surface, making it look as if they are being carried around by the fish. The 24 Solar Terms are an important part of the lunar calendar, and in the international meteorological circles, the 24 solar terms are known as “China's fifth invention”.
