1 and 24 solar terms are the crystallization of the long-term experience and wisdom of the Han working people. This is not just an invention of one person, it is something that people have summed up for a long time.

2. Twenty-four solar terms refer to 24 special festivals in the China lunar calendar, which indicate the seasonal changes.
