What story did Genghis Khan tell before he died, which made his sons' backs cold?

? Genghis Khan told the child a story about his childhood because he was worried that the child would not listen to his decision after his death. In fact, Genghis Khan discovered a snake when he was a child. He told his children that the snake had three heads, and an eagle and Genghis Khan saw the snake at the same time.

However, in order to escape, all three snakeheads got into a hole. At this time, because the area occupied by the three snake heads is larger than this hole, it is said that this snake has been unable to get in and stood still. At this time, the eagle fell from the sky. Genghis Khan was worried that the snake would be caught by the eagle, so he cut off the other two heads of the snake with his sword, and the remaining snake heads suddenly got into the hole.

When his sons heard the story, they actually understood the meaning of the story immediately, so they were all afraid. What this story actually wants to express is that a country can only have one ruler. If a tripartite confrontation is formed, the other two forces will inevitably be weakened in the subsequent process.

Cutting off the snakehead actually means that if three children fight for power and profit, leading to internal turmoil in the country, then two people will inevitably die. Their three sons will feel scared after hearing this statement, so they will be more cautious about the struggle for power and status in the following process.
