You might want to catch up on how ugly things are at CX right now. Tons are quitting or retiring early it's so bad. Go somewhere where you won't get treated like a peasant. From what I heard staff travel is the worst in the business. Hong Kong is noisy, polluted and really REALLY crowded. A lot regret ever going to CX. You'll see if you go. Don't say you were not warned.
