Shen Buhai was known for his cryptic writing style. He was credited with writing a now extinct two chapter text, the Shenzi (申子). During the Han Dynasty, the compilation was organized into two outer chapters, and six inner chapters, but the admeasurement might be different as time goes by. The last mention of this work occurred in 1616, some scholars believe his work did not survived. During the Qing Dynasty, three major attempts were made to reconstruct the contents of this work. The only traces of this work remain in surviving texts which quote from the Shenzi in Qunshu Zhiyao, compiled in 631, and Yilin, compiled around 786.
