What do you think of the solar terms in China?

On the one hand, China's lunar calendar is easy to compile and identify dates. For example, if you look up at the moon, the full moon, around 13456, is absolutely not bad. This is the main body of the lunar calendar; On the other hand, take full care of farmers' agricultural needs and compile 24 solar terms in the solar calendar, so that farmers can have a reliable date to operate their agriculture. This part is a supplementary calendar of the lunar calendar, and I think it is also a very important part.
