Life is a very worthwhile experience, from the height of 10,000 meters down, feeling the experience of total weightlessness. Ctrip's service is excellent. I modified it one day later due to flight problems. Before confirmation, Ctrip helped me to revise it responsibly and called me to explain their progress before I called. In the middle, I made several phone calls to Ctrip temporarily for fear that the supplier would not find me, and they were immediately following up. Great! Although it's a little bit valuable, I'm very satisfied with this kind of service and will come back in the future.
