Grain in Ear is the ninth of the 24 solar terms and the third solar term of summer, indicating the beginning of midsummer. Grain in Ear, pronounced "Mang Zhong" in Chinese, literally means "awned wheat should be harvested quickly, awned rice can be planted". "Mang" is homophonic to the word "busy" in Chinese, indicating that all crops are "busy planting".
This solar term witnesses abundant rainfall and significantly increased temperatures, and most areas have now entered summer. Southern and southeastern China enter the period with most precipitation of the year. The middle and lower reaches of the Yangtze River also enter into the "plum rain season", when there are more rainy days and less sunshine. At the same time, the region can occasionally be affected by tornadoes, hail, drought, and other natural disasters.
