Today, April 20, marks Grain Rain (Guyu), the sixth of the 24 traditional Chinese solar terms. It signals the arrival of more frequent rainfall, providing vital moisture for crops and making it an important season for sowing and tending young plants. In some regions, tea picked during this time is believed to be especially fresh and beneficial for the eyes. Guyu celebrates the life-giving rain of spring and gently reminds us that summer is approaching.
