When is Spring Flower and Autumn Moon-Name two solar terms

Since ancient times, China has been used to taking beginning of spring as the spring and long summer as the beginning and the end of spring. Take beginning of autumn to beginning of winter as autumn, and beginning of winter as beginning of winter and late autumn.

Riddles are not the knowledge of nature's questions and answers. Spring flowers are the flowers of spring. As soon as spring is over, all the flowers in spring are spring flowers. At this time, the spring flowers will "die", which is the long summer. The autumn moon exists in autumn, and it is "gone" in autumn in beginning of winter, and it is also "gone".
