If you are planning on travelling, there are a few simple rules about how to make life easier both before and after your journey.
First of all, always check and double-check departure (启程) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten, my secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.
