The temperature varies all over the country. Will the 24 solar terms change accordingly?

The twenty-four solar terms were actually collected in the Yellow River Basin. Many scholars question that it is certain that the 24 solar terms will change with the change of geographical location and temperature, and the 24 solar terms only give people a foundation and bring certain convenience to life. Because this is a tradition in China, it doesn't mean that the 24 solar terms need to be generalized. The solar terms in the Yellow River Basin should be defined as national solar terms, just as the temperature and humidity between the north and the south are very different, so it is certain that the local people will not sow and harvest in full accordance with the 24 solar terms. Therefore, the solar terms stipulated now are only a concept, not completely stuck in specific days, mainly according to local conditions.

One or twenty-four solar terms are a coordinate, and each region is different. For example, we know that there are solar terms in four seasons, such as cold dew, severe cold and mild fright. Many solar terms have certain customs, such as eating jiaozi in beginning of winter. Each solar term is determined according to geographical location and latitude and longitude, and each region is different. For example, the vernal equinox may be earlier in the south than in the north, because the vernal equinox is the season for farmers to sow, so the 24 solar terms will change with the temperature in the south.

According to the Big Dipper, there were 24 solar terms in ancient times. It is like a 24-hour day, which needs to be used to distinguish the four seasons of the year. There are also many folk customs, such as offering sacrifices to ancestors in spring in some areas, eating noodles in rainy season, sweeping graves in Qingming Festival, and eating Toona sinensis in Grain Rain season, all of which are the customs of southerners. Of course, in summer, autumn crops should be sown in the long summer, and flowers should be sent to the gods during the awning period.

The twenty-four solar terms in China have been passed down for many years, and people have been carrying on this tradition. Every time people go to a solar term, they will carry out corresponding activities. Solar terms, like coordinates, are prepared to record the changes of the four seasons. Therefore, until now, we still regard the 24 solar terms as a timetable for people to do things.
