The validity is pending and needs to be withdrawn voluntarily. If one party causes the other party to enter into a contract against its true intention by means of fraud, coercion or taking advantage of the other party's difficulties, the aggrieved party has the right to request the people's court or an arbitration institution to modify or cancel the contract. If the parties feel that they have been cheated, the civil code gives them the right to cancel the contract or request to change the contract terms.
