Keju Zhidu is a Chinese term that refers to the imperial examination system in ancient China. Imperial examinations were talent selection examinations participated by ancient scholars. It was a system of officer selection by the means of examinations in the imperial societies. Because the officers were chosen from separate section examinations, the system was called Keju in Chinese. The imperial examination first originated from the Sui Dynasty of ancient China. In Tang Dynasty, the system was further improved. In Ming Dynasty, the system reached its prosperity. It had experienced more than 1300 years till the last section of examination in the 27th year of the Guangxu Time in Qing Dynasty. The imperial examinations employed various procedures in different dynasties. The content was mainly Confucian classics, such as "Four Books" and "Five Classics". Some imperial examinations mainly tested the eight-part essay. The eight-part essay is a rigorous style with strict limitation on thesis, format and word count, and the examinees could not release ideas or opinions freely. Such a system baffled the cultivation of talent. In the year of 1905, the Qing government abolished the imperial examination system.
