The problem of the song dynasty in the twenty-four solar terms

Twenty-four solar terms are applicable throughout the country. Twenty-four solar terms originated in the middle and lower reaches of the Yellow River. After thousands of years, they were first compiled into solar term song in the middle and lower reaches of the Yangtze River. After the conversion to the solar calendar in the Republic of China, due to the different natural conditions in different places, the local version of the solar term Song appeared in due course. * * * The following versions are available:
