In spring, everything recovers, the grass is lush, the business is full, and everything is full of vitality. Flowers wither and bear small fruits, and people put on beautiful summer skirts. The hot summer is coming, and pink and white lotus flowers in the lotus pond are also competing to open. In a blink of an eye, the weather turned cold and an autumn wind brushed my face. Yellow leaves fall from trees, just like dancing. Unconsciously, it was cold and snowflakes were flying in the air.
