How cold is winter in Nova Scotia, Canada? How long is winter? Where is colder than Shanghai?

For 50 points, the winter in Nova Scotia is 1 1 until May of the following year. Compared with Toronto, it is much colder, mainly because the maritime climate of the Atlantic Ocean is cold, and it is very humid when it is cold. If we simply compare the temperature, it is much colder than Shanghai.

However, it should be noted that Nova Scotia has heating in winter, both indoors and in the car. The temperature can be maintained above 22 degrees, and there is not much time for outdoor activities, which generally does not exceed 10 minutes. So I personally feel that unless you are engaged in outdoor work, compared with Shanghai, Shanghai feels colder in winter than Nova Scotia.
