The officialdom during Tiansheng's reign was thicker than the grass in the crop fields. Lee Mancang, a farmer from Jeju, was born with a poor mouth, and his mind was filled with the simple pursuit of "making a small amount of money without touching stolen money". When others became officials, they relied on giving gifts to stand in line, but he used jokes to resolve difficulties; when others were intrigues and intrigues, he used self-deprecation to figure out the rules. Who said that low-level officials have no way out? Look at this grassroots man who "has a bottom line in his greed for money". With his clever mouth and half-life sobriety, he became the number one anti-involution person in the official circles of the Song Dynasty.
