1. Climate & Natural Phenomena
Yushui (Rain Water) is the 2nd solar term, occurring around February 18 to 20. During this term, temperatures rise above freezing, winter snow turns into gentle spring rain, and overall precipitation gradually increases across the countryside.
Ancient Chinese phenology divided Rain Water into three distinctive micro-seasons (Penthads / 三候):
獭祭鱼 Otters hunt fish in active rivers and display them on banks like a sacrifice.
候雁北 Wild geese begin their long spring migration back toward northern lands.
草木萌动 Grass and trees awaken with fresh green shoots under moist showers.
2. Lifestyle, Diet & Customs
As the damp spring air settles in, health regimens focus on balancing internal moisture and strengthening the digestive system.
🍵 Diet & Health
Traditional Chinese Medicine recommends eating sweet, naturally warming foods during Yushui to strengthen the spleen and stomach while avoiding overly oily dishes:
- Nutritious Porridges: Chinese yam porridge, lotus seed porridge, and red date soup are widely consumed to aid digestion.
- Spring Bamboo Shoots: Crisp and fresh, early shoots help clear dampness and stimulate healthy appetite.
- Honey Tea: Drinking warm honey water in the morning helps prevent “spring dryness” in the throat.
🏮 Folk Traditions
In Sichuan province and western China, a heartwarming custom called “Visiting In-Laws” (回娘家) takes place during Rain Water. Married daughters return to their parents’ home bringing gifts of stewed pig’s trotter soup with soybeans to thank their mothers and express filial piety.
📜 Classic Poetry
The fine, misty rains of early spring have been immortalized by Du Fu in one of the most celebrated poems in Chinese literature:
《春夜喜雨》 — 杜甫 (Tang Dynasty)
好雨知时节，当春乃发生。
随风潜入夜，润物细无声。
(Good rain knows its proper time, falling right when spring arrives. Drifting with the wind, it slips into the night, moistening all things softly and silently.)
3. Agricultural Wisdom
In rural farming communities, an old proverb states: “Spring rain is as precious as oil (春雨贵如油).”
This light, steady rainfall is vital for winter wheat returning to green and for rapeseed crops entering their growth stage. Farmers focus on conserving soil moisture and applying early fertilizers.
