Legal analysis: According to the specific situation, there are format requirements for the contract to come into effect, which require both parties to sign, seal or fingerprint to prove that it is true. If you don't sign your full name, but stamp or fingerprint to prove that you are me, it is also possible.

Legal basis: Article 493 of the Civil Code of People's Republic of China (PRC). Where the parties conclude a contract in the form of a contract, the place where the contract is established is the place where the parties finally sign, seal or print, unless otherwise agreed by the parties.
