The Ming dynasty (1368–1644) retained and expanded the system it inherited. The Hongwu Emperor was initially reluctant to restart the examinations, considering their curriculum to be lacking in practical knowledge. In 1370 he declared that the exams would follow the Neo-Confucian canon put forth by Zhu Xi in the Song dynasty: the Four Books, discourses, and political analysis. Then he abolished the examinations two years later because he preferred appointment by referral. In 1384, the examinations were revived again, however in addition to the Neo-Confucian canon, Hongwu added another portion to the exams to be taken by successful candidates five days after the first exam. These new exams emphasized "shixue" (practical learning), including subjects such as law, mathematics, calligraphy, horse riding, and archery. The emperor was particularly adamant about the inclusion of archery, and for a few days after issuing the edict, he personally commanded the Guozijian and county-level schools to practice it diligently. As a result of the new focus on practical learning, from 1384 to 1756/7, all provincial and metropolitan examinations incorporated material on legal knowledge and the palace examinations included policy questions on current affairs. The first palace examination of the Ming dynasty was held in 1385.
