What should I pay attention to when my friend flies abroad and can't speak a foreign language, flying from Beijing to Vancouver for the first time and then connecting to Toronto? You'd better write down the detailed steps. Because the plane to Toronto has to transfer from Vancouver, some people go to Vancouver, and some people fly to Toronto. Because I am in Vancouver, I don't need to transfer, but there will be staff reminders and Chinese road signs, but I will transfer to many places, some to small places, some to the United States, but you will fill out a form on the plane, which will write where you are going. But I suggest you try to find someone from China when you are on the plane. If you can't find someone from China, ask a flight attendant who can speak Chinese for help on the plane. They will help you contact China Service. Don't worry, there are many people from China on the plane.

You'd better learn some simple English before you go, or type it on paper for others to see.
