Legal analysis: Same. According to relevant legal provisions, when a contract is concluded in the form of a contract, the contract is established when both parties sign or seal it. Therefore, in principle, when signing a contract, you can sign or seal it. The signature and seal have the same legal effect.

Legal basis: Article 490 of the "People's Republic of China and Civil Code" Where the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it. Laws and administrative regulations stipulate or the parties agree that a contract should be concluded in written form. If the parties do not use written form but one party has performed its main obligations and the other party accepts it, the contract is established.
