Why does Russia call it a bear?

Polar Bear: The polar bear is a metaphor for the sheer size of the country and the resilience of the nation, and I think it is still an appropriate nickname for Russia. If we look at the ferocious, powerful and aggressive meaning of polar bears

First of all, it is related to the geographical location of Russia, so it is called the Arctic.

And because polar bears are large animals, they also fit in with Russia’s vast territory. In terms of politics and military, compared with the hawkish style of the United States, Russia appears conservative, and is very similar to the Chinese traditional concept of bears, that is, bears are blind, honest, and do not attack people at will.
