Which winter is colder, Qingdao or Shanghai?

In terms of latitude, I think Qingdao should be cold. In fact, Qingdao is really cold. The daily minimum temperature in winter in Shanghai is about -3 degrees, 65438+February 25th-February 20th, which is a continuous cold time, sometimes 0 degrees, sometimes1-2 degrees; The lowest temperature may reach -5 degrees, but it is generally not too cold in urban areas.
