“以诗证史”须从时间、人事、地理上来考察“诗”之史料价值, 然“诗”之性质决定了“以诗证史”常常是求普遍史实较易较确, 求特殊史实较难易错, 一旦过于求深坐实, 反而会失真失实。“诗”系如此, 集部、子部、甚至史实之文献, 都程度不同地存在此类情况, 此也是史事考实复杂繁难的一个原因。

When using poetical verses to verify historical facts, people have to examine the value of poems as historical data from angles of time, human affairs and geographical locations.However, the nature of "poetry"tends to determine general historical facts to be obtained more easily and exactly when people use verses to verify them, while particular historical facts are difficult to be verified or are easily wrongly known.People's knowledge of histories may be false in fact if they overstate their verifications by verses.And when people use traditional Chinese literary, philosophical, or even historical books and writings to verify historical facts, the same thing may occur in various degrees.Therefore, it is quite complex and difficult to examine and confirm a historical fact.
