The Theocratic Paradise of Hanzhong
Zhang Lu built in Hanzhong a local regime framed on the Five-Pecks-of-Rice religious community, appointing "libationers" to manage the faithful and the administration in tiers, setting up "charity lodges" by the roadside with free rice and meat for travelers to take, and stressing honesty, self-discipline, light punishment, and lenient rule. In that age of starvation, Hanzhong became for a time a "paradise" the surrounding people flocked to, and he ruled it nearly thirty years.
Judging the Moment, Surrendering His Whole Domain
When Cao Cao led his army against Hanzhong in 215, Zhang Lu, knowing he could not resist, at first meant to surrender; his officers advised burning the treasuries first to show his resolve, but Zhang Lu said "the goods belong to the state," and instead ordered the storehouses sealed and everything properly arranged before withdrawing from Nanzheng. Moved by his refusal to burn the granaries, Cao Cao treated him well, and Zhang Lu, surrendering with his people, was enfeoffed Marquis of Langzhong — the wisdom to judge the moment made him one of the rare warlords of the age to meet a good end.
