It is generally difficult to get the full prize offer, kaust application, and IELTS is only 6. If you pass the whole process, as long as the tutor agrees, nothing else is a problem. Kauste is richer. He has recruited some people from East Asia, Southeast Asia and Singapore, and mainland enrollment is better. Scientific research is basically imported (incidental to digging people), and it is nothing original to survive. As an ordinary university, it is still possible to publish articles. At home, no, the recognition in the world is not high.
As for returning to 985 to teach, first of all, scientific research should be done well to reach the level of excellent international students (even if it may not be possible), then it depends on tutors, then undergraduate colleges, and finally doctoral and postdoctoral colleges, so it is not that important.
