在中国古代契约中有一个重要的角色——中人。他的产生无疑证明了古代人民对契约的高度重视。因而在当时信息相对闭塞,无法沟通有效的信息的环境下,所产生的一种靠经验和知识为他人说合、牵线的职业。不可否认的是,他的存在极大的保障了契约双方的利益,填补了契约双方的“信任落差”。中人大部分产生于宗族之中,和契约当事人难免会有利害关系,但基于当时特定的文化背景,契约在订立过程中并没有对中人采取回避。 In the ancient Chinese contract has an important role - the man. His production undoubtedly proves that ancient people attach great importance to the contract. Therefore, at a time when information was relatively obstructed and unable to communicate effective information, a profession created by experience and knowledge for others to say and match. Admittedly, his existence greatly protects the interests of both parties and fills in the “trust gap” between both parties to the contract. The majority of the Chinese people originate from the clan, and the parties to the contract will inevitably have an interest. However, based on the specific cultural background of the time, the contract did not evade the Chinese people in the process of establishing the contract.
