Yes, every student in Shanshi Normal University can apply for a double degree. You can check it on the website of Shanshi Normal University, but I advise you to think clearly that if you apply for a double degree, it means that you will have no holidays or even weekends in the future. And the tuition is very expensive. I remember it was more than 8000, so I have to check the details. Our teacher does not encourage taking double degrees, because it will not be good for you to find a job in the future. This is still what you get.
