I am on contract with Wasinc. I apologize, but I am not willing to share any details about my job at this time. I am not trying to be an advertising for a contract companies, but I have heard a lot of bad about Wasinc on this website. I must say, I have a good experience with them. I am glad I chose them. They seem to be the fastest in getting you the job. I have a lot of friends, who are with Rishworth and Parc. Parc seems to be the slowest in China, what concerns getting the job as they don't have experience of working with the culture.
The problem I see in China is the cultural problem. It is a very difficult culture to live in, unless you have a sense of humour. You also need a lot of patience as the inefficiency is mind boggling. Having said all that, I think that the right kind of a guy can live in China and be reasonably happy. I have worked in Asia only in the Chinese culture, so I am not aware of the difficulties in other cultures. But "saving face" can be a big problem here.
