So in the eyes of these college students, Xinjiang is not safe. If they travel to Xinjiang, they may die. At this time, there are certainly not many college students who are willing to travel to Xinjiang.
This is not the case in Tibet. Although Tibet is also a gathering area of ethnic minorities, there are still many Han people, and the public security in Tibet is better than that in Xinjiang. In addition, most people in books and on TV describe Tibet as a paradise, a place to pursue faith and a place with great feelings, which college students lack most, so they are willing to travel to Tibet.
In Tibet, college students can find their own beliefs and see a lot of truth, goodness and beauty in the world, so many college students go to Tibet instead of Xinjiang.
