A poem describing the root of the problem

A poem looking for the root of the problem,

Ask the canal so clearly that only the flowing water comes from the source.

I can't recognize the true face of Lushan Mountain because I am there.

Mind your own business, this is a good time on earth.

Warm winds make tourists drunk and make Hangzhou a continent.

Why should a strong brother complain about willow? Spring breeze is not enough for Yumen.
