What is the origin of leather shoes?

Long, long ago, humans walked barefoot.

A king went to a distant country. His feet were sore and numb because of the rugged road and a lot of gravel. After returning to the palace, he ordered all roads in China to be covered with cowhide. He believes that doing so is not only beneficial to himself, but also beneficial to his people, so that everyone can walk without stinging.

But even if we kill all the cattle in China, we can't raise enough leather, let alone spend money and manpower. Although impossible, even stupid, everyone can only shake their heads and sigh, because this is the king's order.

A clever servant boldly gave advice to the king, king! Why spend so much money and sacrifice so many cows? Why not just wrap your feet in two pieces of cowhide? The king was surprised, but he understood at once, so he immediately withdrew and adopted the suggestion. It is said that this is the origin of leather shoes.
