The conclusion of a contract includes two stages: "ordering" and "establishment". "Order" emphasizes that the behavior and process of contracting is the process of contact and negotiation between the contracting parties, including the whole bargaining process before the contracting parties reach an agreement. This stage is regulated and restricted by the system of invitation to offer, offer and counter-offer, resulting in pre-contractual obligations and liability for contracting negligence. The "ceremony" emphasizes the conclusion of the contract and refers to the mutual agreement between the two parties, that is, the two parties reach an agreement on the terms of the contract, at least the main terms of the contract, and determine the rights and obligations of each party.
