Song Qiqiu's authorship was debunked in the 11th century. The Daoist priest Chen Jingyuan 陳景元 (ca. 1024-1094 CE) published the Huashu with his colophon dated 1060 CE, which records a story that Song stole the book from Tan Qiao. Chen heard this story from his master Zhang Wumeng 張無夢 (fl. ca. 960-1040), who heard it from his master Chen Tuan (871-989) who was a friend of Tan Qiao. This contemporary witness said Tan wrote the Huashu on Mount Zhongnan 終南 (Shaanxi) and met Song Qiqiu while traveling through the capital Nanjing to nearby Mount Mao 茅山, which was the center of Shangqing School Supreme Clarity Daoism. Tan said, The transformations of this book endlessly transform. I want you to preface it and pass it on to later generations. Song edited and published the book under his own name. He was posthumously called Choumiu 醜繆 Disgraceful Error.
