Pro: It is to exercise yourself.

You are better at cleaning than before,

You are better at folding quilts than before,

You care more about others than before,

You can run more than before,

You're more manly than before,

About free youth, you feel more beautiful than before!

Disadvantages: joining the army as a soldier is dedication, and the best youth is dedicated to the green military camp. Behind the glory is the best youth.
