Fourth year of Zhiyuan, dingmao; third year of Xianchun of Song: The Song emperor went to the National University to pay homage to Confucius and performed the offering of water-plants. Yan Hui, Zeng Shen, Kong Ji, and Meng Ke were made associate sacrifices; Zhuansun Shi was elevated among the Ten Philosophers. Xu Heng presented five matters of current affairs: first, the institutional scale of establishing the state; second, the essential matters of the Central Secretariat; third, the difficulty of being a ruler in fulfilling words; fourth, sericulture, farming, and schools; fifth, caution over minor details. The Emperor praised and accepted them. [Heng] begged to retire to his native village, and this was granted (History).
