Legal subjectivity:

The legal person in question is the legal representative, and the legal representative’s private seal can replace the signature in terms of legal validity. However, the contract stipulates that it will take effect from the time of signature, and the legal representative’s private seal will take effect from the time of signature. It cannot replace the signature. At the same time, if there is only a private seal but no signature, but the contract obligations have been fulfilled and both parties have no objections, the contract is valid. Legal objectivity:

Article 490 of the "People's Republic of China and Civil Code" If 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.
