Tan reports that several catalogues cited by Fei Zhangfang in LDSBJ are supposed to have been compiled at a date earlier than the translation dates of the scriptures they recorded. Appealing on this basis to one of the principles that Liang Qichao proposed for recognizing forgeries, Tan thus questions the authenticity of the following catalogues:
Fei Zhangfang, in LDSBJ, cites a "Zhi Mindu dou lu" 支敏度都錄 for a single title, the 七女本經; the same title appears immediately afterwards, among a slew of titles listed in evidence for his rather detailed general note on the supposed works of Shengjian/Fajian 聖堅/法堅. These are the only references to this catalogue in LDSBJ; single references to it in DTNDL, KYL, and T2157 are clearly verbatim uses of Fei's own wording.
