Legal analysis: In principle, a check is not foldable, as long as the seal on the check is not creased, because when checking the check, the bank folds the seal on the check diagonally and checks it with the seal card reserved by the bank. If there is a crease here, it will affect the correct judgment of the bank. Serious damage cannot be cashed. If it is serious, you can go to the bank to replace it.
