Create a new selection, click M (rectangular selection box), box out the results, then click B (color shortcut key), hold down alt to absorb the color of the next paper, and then alt+delete to fill in. In this way, the original results are gone.

Click T (text), enter the number you need in the original place, and modify the font size until it is similar to the original level. If you don't like it, just pick up the figures from other courses and put them on.
