Generally speaking, you can't. A paper that won the national second prize cannot participate in the same type of competition or the same type of competition again, because after you have participated in this kind of competition, you already have relevant records. You have already participated in this competition with this paper, and then it is invalid to participate again.

But if you put it into other platforms or other fields, you may be able to participate in such an effect again. Therefore, if you want to participate in the review again, you have to change places, which means you can't submit it twice in the original place, so this is the conclusion above.
