 Two other Legalist texts mentioned in the Han imperial catalog did not survive intact, but lengthy quotations from them in the imperial encyclopedia have allowed partial reconstruction of their content. Shēnzi 申子 is attributed to Shen Buhai, who acted as a chancellor of the state of Hán 韓 in the middle fourth century BCE, and who is credited with major administrative improvement there. Of the original six chapters fewer than three dozen fragments remain intact (Creel 1974). Another text, Shènzi 慎子 is attributed to Shen Dao 慎到 (fl. ca. 300 BCE), of whom very little is known (it is even possible that the figure of Shen Dao a is conflation of several personalities; see Xu Fuhong 2013: 2–8). Of original 42 chapters, seven survived (albeit in an incomplete form) in a seventh-century CE encyclopedy; altogether over 120 surviving fragments of the text are considered authentic (Thompson 1979; cf. Xu Fuhong 2013). In what follows, to avoid confusion between Shēnzi and Shènzi, they will be referred to as works of Shen Buhai and Shen Dao respectively.
