Glad to have helped, but working on a tourist visa is no way to go. Guangdong is one of the worst provinces for foreigners now, they know that too many backpacking ne'er do wells from Thailand have ended up there. That is not to say all backpackers or bad, or that I dislike Guangdong, it is just their visa regulations are very tightly wound. I heard on the old grapevine that the Hong Kong visa run is no longer doable from there, you will be refused one, whereas in another province you may be able to get that much coveted Z visa at china resources in Hong Kong. I'd rather be on a business visa if it was me though, if they find out anything, you could be in a pile of shyte. good luck though, spector
