“The joy of youth is to disobey; but the trouble is that there are no longer any orders.”

少年的快乐在于叛逆， 但问题是(这样做的话, 社会)就没有秩序了.

I totally disagree with this sentence.
For the first part, the joy of youth is not to disobey , neither to obey, but to do the right thing that one sets his or her mind to tdo.

The joy of youth is to disobey ,,,

But the trouble is,, but the problem is,,

What is the trouble? ------
------------that there are no longer any orders.

hope you understand it
