The  24 solar term system is from the traditional East Asian lunisolar calendar that was created over two thousand years ago,
based on the observation of the sun’s annual motion. 
The  24 solar term system embodies traditional knowledge and social practices based on the perception of the regularity of
seasons, astronomical laws and other local natural phenomena occurring in the course of the year.
I create this series illustration to visualize the knowledge and features of each term.
