Legal analysis: the front of the check is stamped with the special financial seal and the company seal, both of which are indispensable. The inkpad is red, and the seal must be clear. If the seal is blurred, this check can only be invalidated, and you can fill in a new one and stamp it again. Stamp the bank reserve seal (usually the financial seal and the legal person seal), and both sides need to be stamped.
