The first floor also makes sense. My niece failed in the college entrance examination and finally went to a vocational and technical college. It's not bad to graduate and work in an enterprise now. Junior college is also better than mixed society.
There are also enterprises that require a minimum college degree or above in recruitment.
I don't know what kind of answer you want, but all this is rude. I don't know if it meets your standards.
