For a while it seemed like this whole thing was never going to happen - but it finally is! The hold-up was due to the Chinese government changing visa rules - before you could go on a visitor visa and switch to a working visa, but now they require you to have the work visa before entering the country. However, it has finally been approved, and should arrive tomorrow (hopefully) or Wednesday. Add two days for processing at the Chinese consulate here and I'm off! I don't have a flight booked yet, but it could be as soon as Friday.
