If your handwriting is small, you can write two lines in the abstract column. You can cross out the wrong abstract with a red line and sign or seal it, but you must make the original trace still recognizable, and then fill in the correct abstract on the line. The amount is written in pencil. You just need to wipe it and write with a pen.

If your handwriting is too big to write two lines in the abstract column, then cross out several consecutive columns diagonally with red strokes, sign or stamp them, and then fill in the correct ones.
