I want to travel to Tibet with my backpack. (1) How many liters of bags are suitable for carrying (tell me the best configuration you think, I am in good health 170)? Go for the first time

1. About the backpack: The size depends on how many things you have. At that time, I didn't bring 50 liters, and a friend brought a suitcase. Don't think so hard about Tibet. I estimate that 50 liters is almost enough. If you mainly rent a car, you can also bring a tow box.

2. Route: If you go back and forth by train, you can only take Lhasa as the point. Namtso still has to go, and the group usually goes back for two days a day. Then go to Linzhi, where the altitude is low and there is no special plateau scenery, but you will see some snow-capped mountains on the road. The Yarlung Zangbo River has a big bend, but it is said that it is more deceptive, so I gave it up. This kind of group tour is usually a two-day tour. If you want to go to Ranwu or the glacier again, you can add another day or two. But this line is usually played along the Sichuan-Tibet line. I really don't know if I have a group tour. Then go to Everest, and you can also play Yanghu on this line. This will take one or four days, and it will take five or six days if it is not urgent. There are also tours in and around Lhasa, such as Potala Palace, Jokhang Temple, Sera Temple and so on. Well, I think ten days is a bit tight. If there is a choice, I suggest going to Namtso and Mount Everest, and then going to Lhasa to play. 10 is tight enough, but there is no time to adapt. And if you go alone and can't make an appointment, you may have to join the group.

3. camera. There is little difference between the 550D and 600D models, which are basically entry-level. I don't think there is any obvious difference. As for the lens, if you are a novice, don't need too much equipment. Just buy a smart lens named "One Mirror Goes the World" with a focal length of 18 (or 17 is uncertain) to 200, thus avoiding the trouble of changing the lens and reducing the weight of the equipment.
