For instance, faced with various former officials and dethroned generals seeking his favor, his subordinates had once advised him to kill them all to prevent future troubles, but Dou Jiande had refused them all, instead choosing to treat these surrendering officers and leaders with a heart of leniency and honesty.
In the territories of Hebei that he controlled, he encouraged agriculture and the development of production, allowing the people to live in peace and contentment, so much so that over two hundred years after his downfall, many local elders still worshipped him.
To summarize, Dou Jiande's performance in politics, economics, and military strategy could be considered top-notch at the time, and he had no glaring weaknesses—he was a multifaceted warrior.
Of course, he was not without imperfections; he, too, had issues such as unjustly killing a leader in a moment of folly or setting a wrong strategic target.
