Jí Tiānbǎo 吉天保 (Sòng) was the compiler of the Sūnzǐ shíjiā jízhù 孫子十家集注 (KR3a0015) — the standard premodern integrated commentary on the Sūnzǐ bīngfǎ 孫子兵法 — drawing together the ten-commentary tradition: Cáo Cāo 曹操 (HànWèi), Mèngshì 孟氏 (Liáng), Lǐ Quán 李筌 (Táng), Dù Mù 杜牧, Chén Hào 陳皞, Jiǎ Lín 賈林, Dù Yòu 杜佑, Méi Yáochén 梅堯臣, Wáng Xī 王晳, and Héshì 何氏 / Zhāng Yù 張預 (Sòng). His own lifedates are unrecorded in standard sources; he was a Sòng official with no surviving full biography. CBDB has no entry for him. The work is variously dated to the late Northern Sòng or early Southern Sòng on the basis of the inclusion of Zhāng Yù.
