When is the winter solstice in geography?

Well, both statements are correct, because generally speaking, it is more than 22 days, but the winter solstice is a solar term of the China lunar calendar, and the date of the lunar calendar does not correspond to the date of the Gregorian calendar we are using now, just as traditional festivals are not fixed on the same day every year. Although there are differences, it is usually only a day or two away, so it is entirely possible to say that the 22nd or 23rd. But if you answer the test paper, just follow the textbook. It won't be your fault ~
