Chunchu jwassijeon (Zuo’s Commentary on the Spring and Autumn Annals, Chunqiu zuoshidian in Chinese) is said to be Zuo Qiuming’s interpretation of Chunqiu (Spring and Autumn Annals), a history book written by Confucius, although it is generally thought that they are two different books. This book includes the annotations by Lin Yaosou, and was published by the Governor of Jeolla-do Seo Seon (1367-1433) in 1431 (the 13th year of King Sejong’s reign) based on an early edition made in China.
