About inter-provincial and inter-school participation in campus job fairs? ! thank you

You can go back to Tianjin University of Finance and Economics to participate in their recruitment, but it is hard to say whether that company in Tianjin is willing to accept this. If it is a good HR, he or she may give you a written test and then an interview, but if it is not a very professional HR, he or she may send you away without a word, and you may not even have a written test. If you want to go back to work in Tianjin in the future, I suggest you try it, even if the other party doesn't give you a chance, it doesn't matter. That's the way to find a job. Try more.
