Hi, I'm 12 y/o and I will be flying from Toronto to Beijing then doing a plane transfer from Beijing to Chengdu to visit my grandparents. This will be my 1st time flying alone, and my 4th time flying there. I don't really remember what we did last time or the time before, and I'm really nervous about getting lost, filling the arrival/departure form, etc. Can you guys give me some tips/advice on what to do? I would greatly appreciate it! Thanks!
