In the United States and Canada, where winter is the coldest in the world, many people have to go through a "war of the century" to remove snow every year to prevent serious snow accumulation and road icing. Canada and the United States, which are the second and third countries in the world in terms of 5.4 million square kilometers and 4.82 million square kilometers respectively, are absolutely "white and clean" when it snows, and we can imagine the huge workload.

In addition, every 2 or 3 cm of snow that has not been cleared will miss the soft snow period, and the road is easy to freeze. Even in case of heavy snow storms, it is better to go out every hour to clean up. If you rely solely on manpower, you should "think about" the weather trend 24 hours a day, and always open the snow shoveling mode of dozens of degrees below zero... Just want to ask - friends, how is your hairline?
