Story:
During the Western Han Dynasty, Jia Yi, a native of Luoyang, was renowned as a child prodigy from a young age.
Emperor Wen of Han, hearing of his great talent, invited him to the capital to serve as a 'boshi' (an official academician) and sought his views on governing the country.
Jia Yi advocated for taking the downfall of the Qin Dynasty as a mirror, constantly reminding oneself to practice benevolent governance, allowing the common people to rest and recuperate, and emphasizing agricultural production to strengthen the nation.
