Are the 24 solar terms in China based on the weather in Luoyang?

Some people think that the 24 solar terms are subordinate to the lunar calendar, but they are actually defined according to the solar calendar. That is, according to the position of the sun on the ecliptic, a year is divided into 24 equal parts. That is to say, the ecliptic is divided into 24 equal parts, and each equal part accounts for 15℃ of the ecliptic. Because the time required for the sun to pass through each bisection is almost equal, the Gregorian calendar dates of the 24 solar terms are roughly the same: the first half of the year is around 6 and 2 1, and the second half is around 8 and 23. There are two formulas:

In the first half of this year,

Come to eight or twenty-three in the second half of the year.
