I have no experience with them but did a Google search. Saw no reviews but did see the latest ad from them over at Dave's Chez Fasciste.

They make it sound good but that salary they offer is awfully low, even for Nanning.

They also use a tactic I really hate: they justify their salary by claiming that the "average local salary" is only 800 RMB per month.

What they DON'T tell you is the lifestyle/standard of living enjoyed by a person making 800 per in Nanning...a dreary, dull gray life of boredom, routine, discomfort, rice-and-vegetables... It will take YOU many times the "average local salary" to achieve a life that won't send you screaming for the nearest airport and a ticket back home.

I also like to point out that you probably aren't coming to China just to work and exist...you're coming here for some travel, some fun, and some adventure. It takes MONEY to make these things happen- please make damn sure you're getting paid well enough to meet some of your goals...not just all of theirs.
