Are the 24 solar terms allowed?

Usually, the twenty-four solar terms prevail.

China's traditional 24 solar terms should have a regional reference. There will also be corresponding weather characteristics. Winter and spring solar terms and actual feelings always feel ten days and a half months ahead of schedule.

Northeast China and northern North China have been in winter for several months. While we were still worried about how they usually spend the winter in such cold weather, they watched us catch cold in the heating room. I don't know whether the solar terms can accurately reflect the subtle characteristics of the four seasons in their place. The southwest and northwest regions are vast, not to mention the accurate existence of solar terms because of the special terrain and geographical environment.

The origin of the twenty-four solar terms conforms to which region. Twenty-four solar terms began with four solar terms in the Shang Dynasty, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After eight solar terms in the Zhou Dynasty, they began to form in the Western Han Dynasty, although every dynasty in the next two thousand years had corresponding details to supplement and improve them.

Judging from the time node of its emergence and development, people's activity center at that time was in Huanghuai area. This can also roughly explain that the 24 solar terms are more summed up by combining the characteristics of the four seasons in this area with farming. This is also consistent with people's more accurate experience of solar terms in this area.
