However, in the process of signing the contract, in order to avoid subsequent disputes, it is suggested that the parties adopt a formal model contract and carefully read the terms of the contract before signing, so as to ensure that they fully understand the contents of the contract and agree to the terms, and avoid signing a contract that is not conducive to them. In addition, before signing the contract, both parties should fully discuss and negotiate the important terms related to the content of the contract, so as to reach an opinion recognized by both parties and avoid the legal effect of the contract being affected by contract disputes.
