I don't know if you are interested in Tibet, which is located on the Tibetan Plateau. The world's most elevated mountains over 8,000 meters are 14 in total, 10 of which are on the Tibetan plateau, and the scenery is very majestic. The local human landscape and Buddhist culture are also quite attractive. And Tibet tourism has been closed to foreign travelers for 3 years and will be reopened in April this year. I recommend Greattibettour, a local Tibetan travel agency recommended by Lonely Planet magazine.
