Wu Yinzhi served as Governor of Guangzhou. In ancient times there was a spring, and people who drank from it became corrupt and wanton; Yinzhi poured it, drank it, paid out double his land tax, and composed a poem:
The ancients said of this water,
That one sip addicted to riches.
If Yi and Qi were to try it,
Their loyalties would never have changed
Moreover, he dwelt in mourning for his mother, showed exceptional etiquette and suffered poverty in his household, and having no choice but to wait until midnight, often hearing a pair of cranes calling in shock at midnight, Yinzhi would always rise and weep, never missing a single time.
