Legal subjectivity:

It depends on the situation: 1. The content of the agreement is legal, and the signing of the agreement is the true intention of both parties. The agreement between the two parties is signed by only one party, but has the seals of both parties. Or if both parties have fulfilled the main obligations of the agreement, the agreement is valid; 2. If the above conditions are not met, the agreement is invalid. Article 490 of the 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 the contract. 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. Legal objectivity:
