As a child, there was always a childish and ridiculous idea; haunting the mind, lingering.

At that time the family lived in the countryside, and there was a deep well in the village; I saw people there fetching water and carrying water; I was full of curiosity and fantasy about that well. After going to elementary school, I learned that the earth is round and full of people. But I'm still worried about that well, and you say what if the well leaks, what if it leaks to the side of the earth? Can people on the other side of the earth come up from the well? Isn't it better to add a lid to the wellhead? Later, I heard that the sea could still drill wells, and I thought, in case the mastery is not good enough to drill the earth thoroughly, the sea water must not flood the people on the other side of the earth!

Now that people are old, this ridiculous thought occasionally emerges.

Friends said that in the future, when science and technology develops to a certain stage, can people dig up the earth and take the subway from one side of the earth to the other side of the earth.
