Beaver has two treasures, one is the raw material used to make perfume, which belongs to the liquid secreted by beaver's gonad; The other is the glossy fur of beaver, which is used to make leather goods. Leather hats made of beaver skin were all the rage in Europe in the 16 and 17 centuries, which was a fashionable luxury at that time. Nowadays, in Canada, the image of beaver can be seen everywhere: patterns on the back of nickel coins, clothing brands (roots), mascots and so on.
In the hearts of Canadians who love beavers, beavers are "smart and noble" animals that can survive by changing the environment. In order to avoid natural enemies and store food, it needs to put the entrance and exit of its nest underwater, so it is busy carrying branches and stones to build dams to stop water most of the time. There is a local saying that beavers are smart enough to bite down trees directionally. It can insert the trunk into the silt of the river bed as a pile, and then build stones, mud and other sundries. The dam it built can withstand the erosion of flood. He is loyal and loves family life. He has only one partner in his life, and he can have three or four cubs in a litter, and he takes good care of them until he reaches adulthood. Many Canadians believe that beaver's diligence and wisdom in improving the environment just reflect Canada's national character.
