What are the precious things about polar bears?

Bear's paw is precious and is one of the eight treasures in ancient times. As early as the Zhou dynasty, it was listed as a tribute for the emperor to eat, and it was a precious delicacy at high-level banquets. Bear's paw is so precious because it is delicious, juicy and nutritious, which is incomparable to other famous dishes. The dried bear's paw contains colloidal protein 55.23%, fat 43.9% and inorganic salt 0.99%. Bear's paw is also a tonic, which can nourish the body, enhance endurance, and has the effects of expelling wind and dampness, strengthening the spleen and stomach, keeping out cold and benefiting qi. In addition, protein, a colloid contained in bear's paw, is of great benefit to sports workers. In addition, wild animals are gradually decreasing, and hunting wild bears is very risky. A bear has only four paws, which is hard-won, rare in output and expensive, and can't meet people's needs, thus causing the situation that paws are extremely precious.
