I have mentioned this on other threads but with Junyao and Spring Airlines, I have thus far purchased tickets on them 3 times.
Never have flown with then as of yet.
Each time, they have cancelled the flight. 30 days prior, 7 days prior and 2 days prior.
Each time ctrip booked me on standby with MU or CA because there was no other flights available at no cost to me.
Not a ctrip issue as much as an airline issue.
