What does English mean?

Let me tell you a joke first: I studied English when I was a child. Students who read "should be interested" are now principals; Those who read Wash in the Sewer become vegetable sellers; People who read the Theory of Causality become philosophers; Those who read "hard history" have become politicians; Those who read "Go to England" became overseas Chinese; I watched "I should be exhausted" and finally became a teacher, describing that the workload of teachers is very tired now. In fact, this word means English.

I hope I can help you, and I would like to go to the next level o (∩ _ ∩) o.
