Personally, I think there should be no problem at all. Last year, the lowest score of Nanchang University was 530, which was 26 points higher than that of Nanchang University. Even the highest score of international economy and trade is 63 points higher than that of Nanchang University.

This year, a line of 505, you have more than 54 points, and there should be no problem in enrolling.

Of course, if it's safer, you'd better call for advice. I wish you an ideal university.
