Legal analysis: First of all, you can negotiate with the other party with the contract. This kind of negotiation can avoid a lot of trouble, and it is also a way for you to defend your rights by renegotiating the contract after reaching an agreement. If negotiation fails, our laws clearly stipulate that a contract with the nature of deception or fraud cannot be established, nor can it be signed when others are in danger, or a contract signed without one's knowledge is invalid. In any of the above circumstances, the contract is invalid.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 148 If a party causes the other party to commit a civil juristic act against its true meaning by fraudulent means, the aggrieved party has the right to request the people's court or an arbitration institution to cancel it.

Article 149 If a third party commits a civil juristic act against its true meaning due to fraud, and the other party knows or should know about the fraud, the defrauded party has the right to request the people's court or an arbitration institution to cancel it.
