Within the Kanripo corpus he is the author of:
- KR1a0066 Yì xiàng yì 易象義 — a 16-juan systematic xiàng-shù-and-yìlǐ synthesizer of the Zhōuyì (composed 1290–1294 at the Shítán jīngshè), giving the most ambitious late-Sòng / early-Yuán articulation of Yì-imagery-derivation theory. Methodologically distinctive for two systematic taxonomies: a 12-class image-taking framework and a 12-school Yì-tradition taxonomy.
- Co-compiler (with 劉惟永 Liú Wéiyǒng and others) of the major Yuán Dàodé jīng commentary-anthology DZ 724 Dàodé zhēn jīng jí yì 道德真經集義 and its introductory DZ 723 Dà zhǐ 大旨 (1299–1300). His own commentary on the Lǎozǐ is cited within DZ 724 under the hào “Shítán.”
Disciple. Yú Qīngzhōng 喻清中 is identified as a disciple of Dīng Yìdōng; Yú’s postface to DZ 724 mentions his own collaborative commentary composed with his master.
His scholarly career thus combines Confucian Yì-canonical scholarship (the Xiàng yì, completed 1294) with Daoist textual-tradition compilation (the Dàodé jīng anthology, 1299–1300). The combination is one of the cleaner late-Sòng / early-Yuán sānjiào héyī (three-teachings-one) intellectual integrations.
