Legal analysis: if the contract has not been signed, you can adjust the contract text or typesetting, or indicate on the blank page that there is no text on this page. If a contract has been signed, since the contract is usually in multiple copies, in order to prevent other parties from adding content on blank pages without authorization, it is necessary to keep an original contract to ensure that the last page of the contract can be proved blank. On the other hand, you can also ask other signatories to issue a blank statement on the last page of the contract.

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.
