Depending on whether you are traveling for poverty or wealth, the poor are about 4000-5000 yuan, and the rich are about 7000-8000 yuan. As for food and shelter, it's up to you to choose. You can take the route from Lhasa to Linzhi, the Potala Palace in Lhasa, Jokhang Temple, Jokhang Temple Barkhor Street, Chubu Temple, Tashi Temple and Mosque. Basongcuo Holy Lake in Linzhi, Nanyigou, Lulang Linhai and Yarlung Zangbo Grand Canyon (the largest canyon in the world). But the most important thing is to prepare anti-altitude supplies in advance before entering Tibet. I wish you a happy life.
