Is the standard of winter the same in north and south?

From a professional point of view, the winter standards in northern and southern China are the same, that is,

For five consecutive days, the daily average temperature is lower than 10℃. Even if winter comes, 1 day is the winter day. So that is to say, when the temperature is lower than 10℃ for five consecutive days, then the first day is winter. (This is the meteorological winter standard in China)

But because of the different dimensions between north and south, the time in winter will be different. The farther south, the later winter. People often think that beginning of winter is winter, so many people in the north will eat jiaozi when they are in beginning of winter, and southerners will eat hot pot.

But in meteorology, it is more scientific to judge winter according to temperature and climate change. However, this does not mean that the solar terms in beginning of winter are inaccurate, because the "24 solar terms" discovered by the ancients were summarized by observing the climate characteristics of the Yellow River Basin, so for people near the Yellow River Basin, beginning of winter is winter.
