"Grain in Ear" is the ninth solar term in the 24 traditional Chinese solar terms. "Mang" refers to the harvest of crops with awns, such as barley, wheat, etc.; "seed" refers to the sowing of millet crops. Summer harvesting and summer planting all happened during this period, so anew round of farming has begun.        Compared with the first eight solar terms, the rainfall during the awn season is still increasing, and the middle and lower reaches of the Yangtze River are about to enter the rainy season.        Plum Rains, often occurring during June and July, refer to the long period of continuous rainy or cloudy weather. This happens to be the time for plums to ripen, which explains the origin of its name. Plum Rains is a good period for growing rice, vegetables and fruits.
