Yangshuo is so beautiful that it's easy to take advantage of.
Yangshuo is so like the "illegal drug" that some get hooked on after they get to know it.
Yangshuo is so full of "foreign addicts" that get paid little for a lot.
Yangshuo's Omeida is a school with an illegal "drug deal" and many beautiful pictures.
Yangshuo's Omeida is an attarctive woman selling her assets to whomever comes (first).

I would like to warn all teachers to keep away from Yangshuo, do not line the dirty pockets of vile and evil people like Buckland and his [edited] cohorts.

Cheers and beers to deals, not drug deals :)
