Spring returns to the earth, and everything recovers: it refers to the scene that spring has arrived, plants have grown, all kinds of small animals have woken up, and everything is full of vitality and prosperity. Willow green and red, singing and dancing: describe the beauty of spring and the joy of everything. When the ice and snow melt, the spring tinkles: when spring comes, the temperature rises, the ice and snow melt into water, and the spring flows tinklingly. Let a hundred flowers blossom and a hundred birds contend: let a hundred flowers blossom and be colorful. Thousands of birds sing together.
