In the fourth year of Zhenguan, Wei Hao wakes up to find himself the talk of Chang'an City as a "fool." He wants no fame, no official career, just to open a shop, make money, and live a comfortable life. Yet a small business drags in princesses, the emperor, and turmoil across the city. Others see him as reckless, but he always manages to hit the mark; others hope for him to stay quiet, but he always stirs the situation into a lively spectacle. Where on earth will the Great Tang push this youth who only wants to get rich?
