Zhang Shoujie was a Chinese scholar of the Tang dynasty. He was the compiler of Rectified Interpretations of the Shiji, often abbreviated as Zhengyi.
This work is an important commentary on the Shiji and is regarded as one of the “Commentaries of the Three Scholars”, i.e. of Pei Yin, Sima Zhen, and Zhang Shoujie.
In detail, these works of the Shiji sanjia zhu《史记》三家注) are the three commentaries known as Sanjia zhu 三家注, which are from Pei Yin 裴駰, Shiji jijie 史记集解 / 史記集解; Sima Zhen 司馬貞, Shiji suoyin 史記索隱, and Zhang Shoujie 張守節, Shiji zhengyi 史記正義.
Zhang Shoujie’s commentary provides a detailed explanation of the geographical names appearing in the Shiji. Since 1196, the Zhengyi, along with the commentaries of Pei Yin and Sima Zhen, has been included in its entirety as part of the standard text of the Shiji.
