Dan's correct, there is not only the CZ won the a court case, but also the Hainan Airlines won the case for taking back the training cost for $3000000.
My recommendation is knock the KA/CX door first. the worse case is go to china and build up your flying hours b4 coming back to Hong Kong. the most important thing for you to fly in china is beware of the contact. the contact with the chinese airlines is f**king sh*t. Anyway a friend of mind has sign a contact for 6 years with the shenzhen based carrier.
