How should athletes immigrate?

After reading your question, I think you have the following plans to try:

If you are a long-distance runner, it is not a bad thing to go there for a run, which not only exercises yourself but also achieves your goal.

If you are a swimmer, cross the sea. The vastness of the sea can greatly improve you.

If you are a player, remember to take your ball and sparring partner with you when you leave.

If so ...

I won't say anything else. Think for yourself.
