What is the story of Kong Jia's "dragon"?

Dragon is the symbol and representative of our Chinese nation. Now we often say that we are descendants of dragons, and dragon totems will be embroidered on the robes of ancient emperors. Although we don't know its real existence yet, there is a very famous story in history, that is, the story of "Kong Jia Jia Long". What is this story about? Is Kong's family a real dragon?

Let's start with the story of Kong Jialong. One day, Kong Jia took the guards to play by the river. Suddenly, he found two behemoths by a river. Kong Jia was frightened at this time. This is not a man-eating monster, is it? A bodyguard said: Your Majesty, these are two dragons, specially sent by heaven to serve you. Kong Jia was overjoyed when he heard this, and hurriedly had two dragons carried into the palace.

After that, Kong Jia called the whole country to order that whoever can tame these two dragons will be rewarded. At this time, a minister said that a master named Liu Lei could tame the two dragons, so Kong Jia quickly invited Liu Lei. Liu Lei, a look, is a thing. Instead of two crocodiles, let Kong build a big pool. In this way, the two dragons survived, but who wanted to raise a dragon died. Liu Lei knew he was in big trouble and thought of a way out.

The next day, I told Kong Jia that from today on, you can let Shenlong practice driving. This is not the best time to get close to the dragon. You need to be strong. Liu Lei sent you a delicious dish, claiming to be a big fish from the East China Sea. Delicious, juicy and nutritious. In this way, the Kongs ate for four days. On the fifth day, no one sent meat, so they sent someone to find Liu Lei. But at this time, where is the dragon trainer? Liu Lei has long run away. At this time, there is a male dragon floating on the surface of the pool, and I don't know how long it has been dead. From then on, Kong Jia became more and more violent, ignoring political affairs all day long, and the country became increasingly chaotic.
