★The origin of the solar term is around central plains of china. So the climate of central plains should be taken as a reference when analyzing other climates with this term. The solar term is not adapted to other countries. However, the degree of Chinese’s attaching importance to it is as to religion. It deepens into Chinese culture. It is very cool that foreigners get their Chinese names with solar terms. The principle of the 24 solar terms is: according to the Sun's position in orbit, every 15 degrees forward is a term; running a week is a year, 360 degrees for the 24 solar terms.
