Two years is not that long. If you are furloughed and you don't have options in the States at the moment, why not spend a few years in China? Could be an eye-opening experience. I would not leave the US thinking that you could cut and run in less than 2 years. Go there expecting to stay at least 2 years and then gut it out. With that said, I would not leave a Captain position in the US for a Captain position in China. Only leave if you get an upgrade out of deal.
Good luck.
