Legal analysis: the contract does not have to be signed by hand, but printed or sealed by both parties, which has the same legal effect as the handwritten signature of both parties. According to the law, if the parties conclude a contract in the form of a contract, the contract will be established when the parties sign, seal or press their fingerprints.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
