Liǎng Hé jīnglüè 兩河經略
Strategic Plan for the Two Rivers (Yellow River and Grand Canal) by 潘季馴 (撰)
About the work
A 4-juàn memorial-cum-strategy work by Pān Jìxùn 潘季馴 (1521–1595), comprising his comprehensive memorials on Yellow-River and Grand-Canal management from his second tenure as Zǒngdū Hédào (River Commissioner) in early Wànlì — when the Yellow River had broken through at Gāojiā yàn 高家堰 and HuáiYáng / GāoBǎo were under massive flood. The work opens with hydraulic-survey maps and concludes with a memorial-letter (recipient unnamed in the text but inferentially the Gōngbù shàngshū Lǐ Yòuzī 李幼滋 who consistently supported Pān’s program).
Tiyao
Liǎng Hé jīnglüè, 4 juàn, by Pān Jìxùn of the Míng. In early Wànlì, the Yellow River broke at Gāojiā yàn; HuáiYáng / GāoBǎo were all flooded vast tracts. Jìxùn proposed building dykes and clearing silt, discussing the strength-and-weakness of the river-flow, restoring the Yellow River’s old channel, listing six points; the imperial edict ordered them carried out. The contents of this book are all his memorials at the time, surveying the southern and northern courses of the rivers; opening with maps and ending with a memorial-letter (the recipient not stated). The text contains the line “by command of the Dàsīkōng (Minister of Works), I went in person to inspect” — examining the time, the Gōngbù shàngshū Lǐ Yòuzī supported the matter from beginning to end; presumably he is the recipient. — Jìxùn served as Zǒnghéwù (River Commissioner) over twenty-seven years in successive tenures; in old age he edited the Héfáng yīlǎn 河防一覽, whose principal teaching is “yǐ dī shù shuǐ, yǐ shuǐ shuā shā” (use dykes to constrain water, use water to scour silt) — and he in the end succeeded by this. The memorials in this collection set out the surveying of conditions, advantages, and abuses with clear distinction; one may see from them the actual sequence of construction. Together with the Héfáng yīlǎn, this work is among the yǒu bì shíyòng zhī yán (words truly serviceable in practice) — not only supplementing the brevity of the Shǐ monograph, but supplying the maps for examination as well. — Reverently presented in the eleventh month of Qiánlóng 46 (1781).

Abstract
The Liǎng Hé jīnglüè is one of the foundational documents of Chinese hydraulic engineering. The 1577 Gāojiā yàn breach was the worst Yellow-River disaster of the Wànlì reign, and Pān’s response — codified in the six-point program submitted at this time — established the canonical late-imperial Chinese hydraulic strategy: confine the Yellow River to a single deep channel between high embankments (shùshuǐ); clear out silt by raising in-channel velocity (gōngshā); restore the historical channel rather than divert into multiple branches; and integrate Yellow River and Grand Canal management as a single system (the liǎng Hé 兩河 of the title). The 1577–81 implementation of this program was successful; Pān’s later Héfáng yīlǎn (1590) is the systematic statement of the doctrine, while the Liǎng Hé jīnglüè preserves the operational memorials. The Sìkù editors explicitly call the work “yǒu bì shíyòng” (truly useful in practice) — high praise in the tíyào corpus, reserved for canonical reference works.

Other points of interest
The 1577–81 implementation period covered by this work coincides with the final phase of the Zhāng Jūzhèng 張居正 chief-grand-secretaryship and benefited materially from Zhāng’s centralized administrative-fiscal capacity. Pān’s success in the 1577 emergency would have been impossible without Zhāng’s backing — though the Liǎng Hé jīnglüè itself is silent on the political mechanics.
