For international friends exploring the traditional Chinese calendar, “Grain Rain” (Guyu) is a term filled with hopes for a bountiful harvest and a rich zest for life. It is the sixth of the 24 Solar Terms, usually falling between April 19th and 21st in the Gregorian calendar. As the final solar term of spring, its arrival signals that spring is drawing to a close and summer is just around the corner.
What is “Grain Rain”?
In Chinese, “Gu” (谷) means grains or crops, and “Yu” (雨) means rain. An ancient Chinese proverb states, “Rain brings up the growth of hundreds of grains.” The name vividly reflects the agricultural and climatic significance of this period: as temperatures steadily rise, rainfall increases significantly. This timely rain acts like nourishing milk for the earth, hydrating newly sown seeds and rice seedlings, making it a golden period for crops to thrive.
Nature’s Signals: The Three Pentads of Grain Rain
Ancient Chinese divided Grain Rain into three pentads (each lasting five days) to record the vibrant changes in nature during late spring:
- First Pentad: Duckweed Begins to Grow.
With increased rainfall, green duckweed starts to rapidly multiply and spread across the surface of ponds and rivers.
- Second Pentad: Cuckoos Flutter Their Wings.
Cuckoos (also known as “Bu Gu” birds) sing cheerfully in the fields and flutter their feathers, as if reminding farmers: “Hurry up and sow your seeds, do not miss the farming season!”
- Third Pentad: Hoopoes Land on Mulberry Trees.
Hoopoes, birds with beautiful crests on their heads, begin to land on lush mulberry trees. This signals that silkworms are about to hatch, and women will soon be busy picking mulberry leaves to raise them.
Poetic Customs of Grain Rain
Grain Rain is not only a critical period for farming but also the origin of many elegant and delightful folk customs:
1. Admiring Peonies
Peonies bloom right around Grain Rain, earning them the affectionate titles of “Grain Rain Flower” and “Flower of Wealth and Honor.” Since ancient times, there has been a tradition of “viewing peonies three days after Grain Rain.” People hold grand peony festivals to appreciate this prestigious flower, renowned for its breathtaking beauty.
2. Drinking Grain Rain Tea
In southern China, there is a custom of picking fresh tea leaves during this period. Nourished by the spring rain, the tea buds are plump, emerald green, and highly aromatic. Legend has it that drinking fresh tea on Grain Rain not only tastes exquisite but also helps clear internal heat, brighten the eyes, and pray for good health.
3. Eating Toon Leaves
In northern China, the period around Grain Rain is when the Chinese toon tree sprouts. The young, tender leaves are highly fragrant, refreshing, and incredibly nutritious. Harvesting toon leaves is known as “eating spring,” symbolizing taking the vitality and good fortune of the season into one’s body.
4. Worshipping Cangjie
In places like Baishui County, Shaanxi Province, there is a tradition of worshipping Cangjie, the legendary inventor of Chinese characters, during Grain Rain. Legend says that when Cangjie successfully created the written language, his deed moved the Heavenly Emperor, who rewarded him by raining down millet from the sky. This custom expresses the profound Chinese respect for knowledge and cultural heritage.
Conclusion
Grain Rain is the magnificent curtain call of spring and the prelude to the vitality of summer. It nourishes all living things with gentle drizzle and teaches the Chinese people to follow the rhythm of nature and work diligently.
Next time you see blooming peonies or sip a cup of fragrant fresh tea during this season, take a moment to feel this millennia-old Eastern wisdom: nourished by the spring rain, quietly await the blossoming of life.
