The earth is round, and any object that walks on the earth takes an arc, sometimes far away, sometimes very close. We can only understand translation and rotation according to students' cognitive level (that is, learning stage).

In primary school, according to the definition of translation, when an object moves from one position to another, its shape and size do not change, which is translation. Then, when a person walks from one place to another, the person himself has not changed, which can be said to be a translation. This has nothing to do with how this man came.
