In Romance of the Three Kingdoms, why did Yu Xun commit suicide by taking medicine after receiving Cao Cao's empty lunch box?

There is such a thing in the Three Kingdoms. At that time, Yu Xun opposed Cao Cao's establishment of Wei State, so Cao Cao gave Yu Xun an empty box. After that, Yu Xun understood the meaning of the empty box and committed suicide. What does this mean? Why did Yu Xun choose to commit suicide?

In fact, Cao Cao did this out of kindness. He knows that at this time he is about to achieve the most important thing in his life, which he has worked hard for most of his life, so for him, anyone's opposition will be ignored. At this time, Yu Xun opposed Cao Cao and was embarrassed to come forward to solve him. Besides, the relationship between them is really like bosom friends, so Cao Cao sent an empty box to Yu Xun to understand. This empty box has three meanings, and Yu Xun also saw it, so he ended his life.

Let's start with the first one. An empty box symbolizes an empty coffin. Cao Cao gave him such an empty box, which is undoubtedly an empty coffin. Empty boxes are used to hold things, and empty coffins are used to play dead. In this way, the meaning expressed by Cao Cao is very clear. He just wanted Yu Xun to die, but he couldn't kill him himself, so he sent a box to let him end his life. Yu Xun also understood Cao Cao's intention. He knew that there must be a person in this coffin, either he or Cao Cao. Cao Cao can't go in, so only Yu Xun.

The second layer means that the box that Cao Cao gave to Yu Xun at that time was not one layer, but three layers. If you think about it carefully, it is not difficult to find the problem. At that time, Yu Xun had been following Cao Cao for nearly 30 years, which means that the three layers represent the past 30 years ago, and the empty box represents that everything is over and there is nothing left. Yu Xun also understands that Cao Cao just wants to tell him about his efforts in the past 30 years. In your argument that you insist on protecting and helping the Han Dynasty, everything in Hua Song is empty. Gao said, "You have made up your mind, and you can't go against it." .

Finally, the box is used to put things. The box that Cao Cao gave Yu Xun was only used for eating, but Cao Cao gave Yu Xun an empty box to tell him that before you worked for me, I gave you a salary and a job, but now that you are against me, I will definitely not give you any salary. Giving Yu Xun an empty box means that he is nothing in Cao Cao's eyes, and he is also an adviser abandoned by Cao Cao. Since Yu Xun left? A job? Then his life may be out of his control. So now he might as well respond to Cao Cao with suicide.
