China and Inner Asia
The extant work, Nanxuan ji《南轩集》, of Zhang Shi张栻 (1133-1180) was edited by Zhu Xi朱熹 (1130-1200) after Zhang Shi passed away. I found that not all of Zhang Shi’s letters were collected in the Nanxuan ji, and Zhu Xi did not write anything to talk about the selection criteria.Therefore, it is necessary to figure out how Zhu Xi selected Zhang Shi’s letters when editing the Nanxuan ji. While dating Zhang’s correspondence, I rediscovered some missing letters of Zhang Shi preserved in other texts, and this inspired me to explore Zhu Xi’s selection criteria. Moreover, after reading the letters from others to Zhang Shi, I also found that more than 90 letters of Zhang Shi were not collected into the Nanxuan ji; therefore, by studying these letters, I can speculate on and explore Zhu Xi’s selection criteria for selecting which of Zhang Shi’s letters to include. I think the most important selection criteria of collecting Zhang Shi’s letters was whether the letter was related to scholarship. Meanwhile, Zhu Xi also did not include the family letters of Zhang Shi and some other letters which he thought were meaningless. Besides, we can also know the basic standards of collecting letters in works of Southern Song dynasty by analyzing the Donglai ji《东莱集》of Lü Zuqian (1137-1181) and Hui’an wenji《晦庵文集》of Zhu Xi.
