Li Wei, the son of a salt dealer, became an alternate county magistrate by donating money, but he had no choice but to live in the capital. By chance, he found the private seal for Prince Yong and was re-employed as the prefect of Suzhou. When he first entered the officialdom, he was shocked every step of the way when he was faced with the messy situation of the weaving fortune tree covering the sky with one hand, the grain shortage, the secret granary, and the serial murders. Li Wei used his market wisdom to break the situation, secretly visited the dock, re-examined old cases, visited granaries at night, and outsmarted the powerful, and abruptly opened up the corruption scandal in Suzhou. He inspected grain collection, cleaned up salt classes, redressed unjust cases, and brought down Futong. From a despised donation official, he gradually became a capable minister that Yongzheng relied on.
