After investigation, the court finds that if the signature is forged by the relevant person, it can be fined and administratively detained. Moreover, forging the signature of a party is suspected of providing false material certification. If the circumstances are serious, it may constitute a crime and will be investigated for criminal liability in accordance with the law. Even the agent of the party cannot forge the signature of the party.
