In the Xia Dynasty, there was an "expert in dragon breeding" Liu Lei. According to legend, he kept two live "dragons", which should be a kind of deer that people had never seen before. According to legend, Kong Jia, the eighth monarch of Xia Dynasty, found two dragons, one male and one female, when he was out hunting. So people tried their best to bring the two animals back to the palace, and at the same time let special people build a palace for the two animals to live in.

But no one can raise these two "dragons", so the monarch issued an imperial edict to let all ministers go to the whole country to recruit talented people to raise dragons. Later, a man named Liu Lei was brought in to raise dragons, but he only knew how to raise them, but that's all.

Later, one day, Kong Jia heard from the minister that all the immortals used to ride in dragon-drawn cars, so he wanted to try, so he asked Liu Lei to prepare, but Liu Lei could only raise them, but he couldn't domesticate them. As a result, one of them was exhausted. There was nothing he could do, so he killed both dragons, skinned them and sent them to the emperor. The emperor had never eaten so much.

Liu Lei's behavior of cooking dragons for Kong Jia is very interesting, because at that time, after all, no one had eaten dragon meat. I don't know whether this dragon meat can be eaten or not. What if Kong Jia is poisoned? Liu Lei did not dispose of the dead dragon, but cooked it and sent it to Kong Jia, the monarch. What is the motive may only be known to him. In the long river of China's 5,-year history, there are many legends of dragons. As the spiritual totem of China, it has deeply entered the history of China.
