In 1565, he submitted a memorial strongly criticizing the Jiajing Emperor for the neglect of his duties and bringing disaster to the country,[4] for which he was sentenced to death in 1566.
Hai devoted considerable time to investigate these cases, pressing for the lands' return to their previous owners, but was in turn accused by officials of violating procedures and encouraging frivolous complaints and impeached by Tai Feng-Hsiang, a supervising secretary (御史, yushi).
He then wrote a play for Peking Opera titled "Hai Rui Dismissed from Office", which he revised several times before the final version of 1961.
[1] Wu's play was interpreted by the Gang of Four member Yao Wenyuan as an allegorical work, in which the honest, moral official Hai Rui represented the disgraced Chinese communist marshal Peng Dehuai, who was purged by Mao after criticizing him as corrupt.
The November 10, 1965, an article in a prominent Shanghai newspaper, "A Criticism of the Historical Drama 'Hai Rui Dismissed From Office'" (评新编历史剧《海瑞罢官》), written by Yao, began a propaganda campaign that eventually led to the Cultural Revolution.
[6] Yao's campaign led to the persecution and death of Wu Han, as well as others involved in related works, such as Zhou Xinfang for his opera Hai Rui Submits His Memorial (海瑞上疏).
