Why is the winter solstice calculated according to the solar calendar

Four seas network: the winter solstice is one of the traditional 24 solar terms in China. It originated in the spring and Autumn period and the Warring States period. So the question is, the solar calendar was introduced into China after the Republic of China. Why does the winter solstice be calculated according to the solar calendar? Let's take a look at it!

The lunar calendar takes one cycle of the moon as one month, such as the first and second lunar calendar; the lunar calendar takes one cycle of the sun as one year, with 24 solar terms, such as the spring equinox and the winter solstice as the lunar calendar. The lunar calendar is not the first day or the first day. China is a large agricultural country for thousands of years, and the lunar calendar is particularly important in production and life.

The solar calendar, not to say much, all understand that it takes one cycle of the sun as one year, so it's synchronous with the lunar calendar, just different in division, and the difference is seven or eight days. Therefore, each winter solstice, the solar calendar date is roughly the same, before and after the difference of up to two days.
