Legal analysis: if fingerprints and signatures exist at the same time, one of them is executed by myself, which means it has legal effect. In order to conclude an effective contract, both parties must abide by the stipulation that a legally established contract shall take effect upon its establishment, so as to achieve the expected purpose. In the process of concluding a contract, the parties should correctly understand the relationship between the establishment of the contract and the entry into force of the contract.

Legal basis: Article 502 of the General Principles of the Civil Law of People's Republic of China (PRC) stipulates that a contract established according to law shall take effect upon its establishment, unless otherwise stipulated by law or agreed by the parties. In accordance with the provisions of laws and administrative regulations, if the contract should go through the approval procedures, such provisions shall prevail. If the failure to go through the formalities such as approval affects the effectiveness of the contract, it will not affect the performance of the obligation clauses such as approval and the effectiveness of relevant clauses in the contract. If the party that should go through the formalities for approval fails to perform its obligations, the other party may require it to bear the responsibility for violating its obligations. The modification, assignment and dissolution of a contract shall be subject to the provisions of laws and administrative regulations, and the provisions of the preceding paragraph shall apply and shall be subject to approval.
