Article 185 of the Contract Law is a gift contract in which the donor gives his property to the donee free of charge and the donee expresses his acceptance of the gift. Gift is a legal act of both parties, that is, the donor and the donee reach an agreement voluntarily through consultation according to law, and the contents of the agreement shall not violate the mandatory provisions of the law.

Article 77 The parties may modify the contract through consultation.

If you think there is something unclear in the agreement, you can negotiate with the other party to modify the content. Re-sign the gift agreement or modify the original contract for the unclear content, and indicate: both parties agree to this modification, and the date of modification shall be signed by both parties.

It is best not to unilaterally modify the signed contract, because it is impossible to determine whether the "unknown things" will change the basic content of the contract, directly affect the contractual rights and obligations of both parties, and may seriously lead to the invalidation of the contract.
