shǐ cái sān cháng 史才三长
Three Strengths of a Good Historian
指修史或治史的人所必须具备的史才、史学、史识等三项专长。是唐代著名史学理论家刘知几提出的史学观点。“史才”指史书撰述能力；“史学”指丰富的历史知识和资料；“史识”指分析和评判历史的思想见识。刘知几认为，修史或治史的人必须同时具备这三种能力，其中“史识”最为重要。
According to the renowned historiographer Liu Zhiji of the Tang Dynasty, those who study and write history must have three strengths, namely, the ability to compose historical works, rich knowledge of history and historical materials, and deep insight that enables them to analyze and evaluate history. Liu believed that deep insight in analyzing and commenting on history was the most important of the three qualifications.
