“Rain Water” (Chinese: 雨水) is the second solar term of the 24 solar terms, and this year falls on February 19. This term marks the start of warming days, thawing snow and increasing rainfalls, hence the name “Rain Water.”

As the days get warmer, the precipitation increases and brings more rain than snow. The chilly winter gives way to the warm spring at this time. While blessed with warm spring breezes, the period following “Rain Water” also accounts for the most frequent cold waves in the year and unpredictable temperature fluctuations.

According to an old Chinese saying, the rainfall in spring is as precious as oil. In northern China, spring drought is common, and the precipitation of this season accounts for only 10% to 15% of the annual average rainfall.

Therefore, Rain Water is considered a critical irrigation period when the day gets warmer and rainfall increases.
