The solstice in winter is the solstice, right?

The solstice in winter is the solstice. Because the summer solstice and winter solstice can be referred to as "solstice" and "solstice" for short, which is the earliest and most important solar term. In fact, among the 24 solar terms, there is no such thing as four days, only two halves. The vernal equinox is the vernal equinox and the autumnal equinox, and the second solstice refers to the summer solstice and the winter solstice. This answer is for reference only. Don't be blindly superstitious.
