The Classic of Filial Piety was to be one part of the imperial examination during the Shunzhi reign, from that time the subjects chosen from the Classic of Filial Piety began to shape the literary style of the imperial examination and established a particular standard for the imperial examination. After undergoing several periods of change, this style of the imperial examination was given up in the Qianlong reign. Studying the changes of the Classic of Filial Piety literary style of the imperial examination will not only show the intentions of the emperors, but also help us to understand the standard of the Imperial Examination in Qing Dynasty．
