And I think you change terminals also, which means a longer time to physically walk to security and boarding. As a foreigner, your documents for Tibet will be scrutinized carefully at domestic check-in. Since cutoff times for domestic check-in are normally 30 minutes in advance of departure (but may be earlier for the LXA flight), I think you will be very tight on time. I personally would not have scheduled this tight a connection.

Try to sit somewhere on the SIN-CTU flight that allows quick deplaning, pray there's no fog delaying inbounds into CTU, and pray the bags come off quick. If *G on any airline, get bags tagged priority in SIN, usually Asian's are pretty good about getting the priority bags off first. Customs will be a quick walk-through, then get up to CA domestic check-in fast though I think you'll be switching from T1 to T2. If this is all on one ticket and you miss the connection, CA should put you on the afternoon flight...assuming there are any available seats on it. If the ticket is endorseable to another airline, I think Sichuan Airlines has a morning flight or two but CA would need to be pushed hard to put you on them rather than their own metal.
