There is no doubt that being a mentor requires a lot of effort. You may not have time to study or do other things, but you can also gain a lot and improve your ability in many other aspects. The advantage is that, first of all, you get exercise yourself, and your work and rest will be regular. Anyway, I think the instructor is in good order. Secondly, there will be a group of buddies. Then, there will be a group of Xiong Haizi, and of course Aruba on the last day of military training, haha. It is worth mentioning that instructors are passed down from generation to generation. For a senior tutor, the alumni association will be kind and the tutor will be more kind.
