If you enroll students independently, you can't get a domestic diploma or a foreign diploma without going abroad. In this case, you must go abroad, otherwise the book will be read in vain.
If it is a cooperative school with unified enrollment nationwide, you must have at least a domestic diploma if you don't go abroad. As for foreign diplomas, it depends on the specific professional settings of your school.
You need to ask the school about your specific situation, and then I can give you a more prepared answer. I hope it helps you.
