Is Laba Festival the coldest time?

Laba and Great Cold are the same day this year, so that day is the coldest time. Although there is still some time before March 949, the temperature has dropped a lot since the holiday. In many areas, the daytime temperature has dropped below 0 degrees, and in many areas of Northeast China, the daytime temperature has even dropped below minus 10 degrees. Although some meteorologists have said that it will be very warm this winter, I believe many people believed it ten days ago, but in recent days they have begun to doubt what the experts said, because judging from the current weather conditions, it is impossible to see it at all.
