Legal analysis: Yes. When a natural person concludes a contract, the natural person who concludes the contract generally signs or stamps his or her name; when a legal person or other organization concludes a contract, the legal representative of the legal person or the person in charge of another organization generally signs or stamps the official seal of the unit.

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.
