Life

Early career

Although the year of his birth is uncertain, it is known that Du Shi was born in Henei, Henan province. Du Shi became an Officer of Merit in his local commandery before receiving an appointment in 23 as a government clerk under Gengshi Emperor (r. 23–25), following the revolt against the Xin dynasty usurper Wang Mang (r. 9–23). However, Du soon after swore his allegiance to Emperor Guangwu of Han (r. 25–57), who is considered the true founder of the Eastern Han dynasty (25–220).

Censorate officer

Under Emperor Guangwu, Du Shi was appointed as an officer in the Censorate and was in charge of monitoring affairs and upholding law and order within the new capital at Luoyang. When the undisciplined troops of the military officer Xiao Guang (d. 26) ran rampant in the capital city and terrorized its inhabitants without any perceivable action on Xiao's part to prevent it, Du Shi had him arrested. Du had Xiao summarily executed without explicit consent from the throne, sending in a report of the event only after the execution. Guangwu was not displeased with this, as he called him into his court to grant him an insignia which justified his actions. Shortly after this event, the bandit leader Yang Yi (d. 26) caused a major disturbance in Hedong Commandery, which Du Shi was sent to quell. When word of the arrival of Du Shi's forces in the region reached Yang Yi, he planned to flee across the Yellow River. However, Du Shi anticipated this, sending a raiding party to burn the boats Yang Yi intended to use for his escape. After conscripting troops from the Hedong Commandery, Du Shi led a surprise ambush with a cavalry unit that dispersed Yang's bandits and annihilated them.

Administrator

For three years, Du served as a county magistrate in Henan province where his administration gained wide acclaim from provincial authorities. Afterwards, Du distinguished himself as a Commandant in Pei and in Runan. In 31 he was appointed as an administrator over Nanyang. While serving there, he had an array of dykes and canals built for land reclamation and growth of local agriculture. It is here that he also developed a water-powered reciprocator for bellows in smelting cast iron, a machine which reportedly saved an enormous amount of physical labor. It is recorded that the locals were so fond of him that they often referred to him as "Mother Du" and compared him to noteworthy figures of history, such as Shao Xinchen of the Western Han era.

Du Shi was by all means a local administrator, yet he also made recommendations to the imperial court on policy issues. He recommended that the Tiger Tallies system be reinstated. This was a means for imperial authorities to check possible official corruption in the forgery of mobilization of troops for war. Du also nominated several minor officials he deemed worthy as candidates for higher posts in the capital, including Fu Zhang. In a memorial of 37, he urged the court to consider Fu as the next Imperial Secretary.

Death

Du Shi's reputation was damaged in 38 when he was accused of having one of his retainers sent to kill a man out of vengeance for his brother. In that same year, Du became ill and died. Despite Du's long-standing official career, the Director of Retainers Bao Yong reported that no proper funeral ceremony could be arranged for Du, since Du was nearly broke when he died. However, the Emperor had an imperial edict made which granted Du a proper funeral ceremony at his commandery residence in the capital, along with silk to pay for the expenditures.
