Chunjiang weather

In ancient times, when people knew little about meteorology, poets who were good at discovery could always describe the changes of solar terms in nature delicately and realistically through their keen brushstrokes, and there were many scientific reasons. "Peach blossoms outside the bamboo are three or two, and spring water warms the duck prophet" is an example.

In the late winter and early spring in the south of the Yangtze River, the weather is still relatively cold, and the average temperature is around 10 degrees Celsius. There are often severe frost and even residual snow. In this cold weather, when dogs, cats and other animals are still squatting by the fire and under the eaves, there are already groups of ducks playing in the cold water of ponds and streams. This phenological sign tells people that the cold weather is about to pass, the temperature is beginning to rise, the water temperature in rivers and streams is getting warmer, and spring is coming.

Why is "Spring River Plumbing Duck Prophet"? Why do ducks have fun in cold water and have no chill? It turns out that ducks are covered with dense feathers, which store air in them and play a good role in heat preservation. In winter, we wear down jackets and duvets, which is why we feel warm. In addition, the river begins to thaw in spring. Although the chill has not disappeared, the temperature has begun to rise. Among them, ducks can feel the change of water temperature first, so they can't wait to dive into the water to swim. This phenomenon was observed by the poet, who condensed the ancient saying "Duck Prophet in Spring River Heating".
