Rain gives birth to hundreds of valleys, clean and bright.

Grain Rain, the last solar term in spring, is also the second solar term "Zhong Qi" in March of the lunar calendar, which means "Rain gives birth to hundreds of valleys", and is characterized by continuous spring rains.

The word "valley" representing crops was written as "valley" in ancient times, and "valley" is more of a geographical title.

Before and after Grain Rain, the weather turned warmer, the rainfall increased, and the flow of springs and streams increased, which was beneficial to crop sowing and irrigation growth.

In ancient works, Grain Rain is divided into three stages: the first stage is when Ping was born; The second time, pigeons blow feathers; The third stage is from Dai Sheng to Sangzi. It was after the rain that the rainfall increased, duckweed began to grow, then cuckoo began to remind people to sow, and then Dai Sheng bird began to be seen on mulberry trees.

Grain Rain is an important time for health preservation in the eyes of the ancients, so we should adjust our work and rest and diet to adapt to the alternation of spring and summer.

The custom of "picking tea" and "drinking tea" in Grain Rain solar terms has been passed down to this day.

Grain Rain is the best time to pick Longjing before the rain, because tea trees are in a state of one leaf and one bud, commonly known as one flag and one cannon. This is Longjing tea, which is made of picked tea leaves, and its fragrance is the most mellow.
