In what season butterflies fly around and ducks swim around in the water?

In Miss Chun's article, it is written like this. Spring comes to us quietly, grass sticks out from the soil, rape flowers are smiling, and groups of butterflies are dancing in the sea of flowers. The river has thawed, and a group of lovely ducklings are playing on the water.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain.
