档案的凭征作用,在《左传》记载的一些史实中,也被显示出来。那时,诸侯之间有了争端,往往引证盟约的誓言的文字纪录,档案便成了最可靠的根据。如蔡卫两国关于政治地位之争,就是一个例子。定公四年正月,刘文公假周天子名义,在召陵会合诸侯,准备结盟伐楚。盖因楚国恃强凌弱,无礼拘留蔡侯三年,不让他返国。蔡侯立志要报复,所以这次盟会得以实现,正是蔡侯不断努力的结果。当时在周王朝辖下,共有十八个国家派了代表来参加,可以说是盛况空前了。且说卫侯在来参加会盟之前,他看到与会诸国,并非团结无间,众口纷纭,争执在所难免。所以特别选拔了个臣子,名叫祝佗字子鱼的,随同前来。祝佗本是掌管祭祀的下吏,地位很低,非有社稷变迁是不得出境的。但是因他博学而有才辩,熟悉国际盟约的情况,所以终于还是让他来了,以应付可能发生的意外事件。果然不出所料,在盟会即将举行时,一个不寻常的传闻散布开来,使卫侯听了大为震惊。原来有人正拟在结盟仪式进行的时候,要把蔡侯的位次排列在卫侯的前面。在卫侯看来,这无疑是对他的政治地位的重大贬抑。卫侯当下就差祝佗去询问周王朝中央的代表苌弘,他也是主张蔡先于卫的一个。苌弘答道: “蔡侯的祖先——蔡叔,本是卫侯的祖先——康叔的兄长,按照其祖上的长幼排列先后次序,那么把蔡侯列于卫侯之前,不也是合理的么?” The merit function of the archives is also shown in some historical facts recorded in Zuo Zhuan. At that time, there was a dispute between the princes, often quoting the verbal record of the oath of the Covenant, the archives has become the most reliable basis. One example is the controversy over the political status between the two countries. Ding Gong four years lunar January, Liu Wen Gong false Son of Heaven in the name of summoned to meet vassal, ready to alliance Vault Chu. Cover because of bullying Chu, rude detention Cai Hou three years, will not let him return. Cai Hou determined to retaliate, so this union will be achieved, it is the result of continuous efforts Caihou. At that time, under the jurisdiction of the Weekly Dynasty, a total of 18 countries sent representatives to attend, which can be said to be unprecedented in popularity. He said Wei attended the League before the meeting, he saw the participating countries, not unity, all disagreed, the dispute is inevitable. Therefore, a special selection of a courtier, named Zhu 佗 word fish, come along. I wish this book is in charge of the sacrificial officials, the status is very low, there is no change in the boat is not allowed to leave the country. However, because of his erudite knowledge and familiarity with the international covenant, he finally made him come to deal with possible accidents. As expected, unexpectedly, an unusual rumor spread out at the imminent appearance of the UNITA, which shocked Wei. Someone originally intended to be at the ceremony of the alliance, we should arrange the rank of Cai Hou in front of Wei. For Weihou, this is undoubtedly a major derogatory measure of his political status. Wei Hou poor poor wish to ask the representative of the Central Government of the Zhou Dynasty 苌 Hong, he is also the advocate of Cai before the one.苌 Hong replied: "Tsai Hou’s ancestors - Cai Shu, this is the ancestor of Wei Hou - Uncle Kang’s brother, according to their ancestors of the elders arranged in the order, then the Cai Hou listed Wei before, not Is it reasonable?
