This is an extraordinary tale of how an ordinary scholar becomes a prince of a different surname (from the imperial family). With his wife, he lives in poverty, and to repay his wife's unswerving loyalty to him, he goes to the capital to take the Imperial Examination. By chance, he helps solve a court case and is then tied into the national affairs of the country.
