The World Trade Organization is a grand hotel after all. You can always learn something if you really want to learn, but it is up to you to decide how to develop in the future.

For example, if you want to be a foreman or a manager by your own efforts, it's not bad.

If you want to learn some financial knowledge, you can go to cashier or accountant.

If you want to learn some skills of opening a restaurant, it's OK

Or learn to deal with people in it, and it's good to exercise your interpersonal skills.

In short, you can learn a lot.
