The Tang Dynasty's Number One Corrupt Official

In the first year of Taizong's reign, the bloodshed at Xuanwu Gate had yet to fade. Then a young boy appeared out of nowhere, sweeping through the Tang like a spring breeze. He was greedy, lecherous, timid, and cowardly, possessing every flaw imaginable. But really, he was nothing more than a simple corrupt official. Still, he had a motto of his own. What's the point of pocketing a few coins from children? If you're going to be corrupt, go big! The powerful and wealthy despised his character, yet coveted the things he controlled. Emperor Shimin of Tang tried again and again to have him executed, but was forced to let him off each time. After all, without him, the Great Tang would lose a million troops!
