history
From Wei Zheng's (魏征) Tang memorial 《谏太宗十思疏》 (Ten Reflections Presented to Emperor Taizong), 637 CE. Opening passage: 臣闻求木之长者，必固其根本；欲流之远者，必浚其泉源 - 'I have heard that one who wishes a tree to grow tall must first make firm its roots; one who wishes a stream to flow far must first dredge its source.' Wei Zheng was famous for remonstrating bluntly with Emperor Taizong - and being heeded.
usage
Paired couplet - often quoted with 欲流之远者，必浚其泉源. Standard reference in policy, management, and pedagogical writing about foundations vs. surface effects.
