In 2008, Tsinghua University of Beijing acquired a corpus of manuscripts written on bamboo slips from China’s Warring States period (c. 300 BCE) and established the Research and Conservation Center for Unearthed Texts directed by renowned scholar Li Xueqin 李學勤(1933–2019) to edit and publish them. A panel of experts convened to evaluate the manuscripts said of them:These Warring States bamboo slips are tremendously valuable historical artifacts, whose contents speak to the very core of traditional Chinese culture. This is an unprecedented discovery, one which will inevitably attract the attention of scholars both here and abroad. It promises to have a lasting impact in many different disciplines, including but not limited to Chinese history, archaeology, paleography and philology.The series Tsinghua University Warring States Bamboo Manuscripts: Studies and Translations, brings together a group of international scholars to study and translate the texts. Volume 6 is devoted to a set of historiographical texts including the Lady Wu of Zheng Admonished her Child鄭武夫人規孺子and other stories from the Spring and Autumn period.
