What do you think of the sentence "winter in the north can really freeze people's ears off"?

I am an authentic child in the northeast rural area. I heard such words when I was very young. When I saw such words, I also felt that I was back to my childhood. Adults often whispered some jingles about the seasons, but so far I can't remember any of them. In winter in Northeast China, the outside temperature is very low, mostly 2-3 degrees below zero. Now it is not so cold in winter, but when I was a child, my ears were really frozen. Cold weather easily caused poor blood flow, so my ears were red and purple, and even in some areas.
