Why did Cao Cao keep shaking his head after listening to the ministers' statements?

Because these officials' methods are unrealistic, either too troublesome or impossible to implement.

When Cao Chong was five or six years old, he was as knowledgeable and judgmental as an adult. Once, Sun Quan sent a giant elephant. Cao Cao wanted to know the weight of the elephant, so he asked his men, but they didn't know how to weigh it.

Cao Chong said: "Put the elephant on the big ship, mark where it reaches the water surface, and then let the ship carry other things, weigh them and compare them." Cao Cao was very happy and did it at once.
