To prevent being hunted by Yuan soldiers, the group traveled day and night for four days without rest, finally entering the Qinghai-Tibet Plateau.

Entering this area meant they were out of the Yuan Court's jurisdiction, and everyone was finally safe.

During the Yuan dynasty, this place was called the Xuanzhengyuan territory, part of the Tubo region, which is now Tibet, although it was still considered Yuan territory.

At the height of the Yuan dynasty, this area could still be controlled.
