Zheng Changtu

Zheng Changtu (鄭昌圖) (died April 6, 887?), courtesy name Guangye (光業), was an official of the Chinese dynasty Tang Dynasty. He served as a chancellor in the administration of the pretender Li Yun, who claimed the throne in competition with Emperor Xizong. After the deaths of Li Yun and Li Yun's main proponent, Zhu Mei, Zheng was executed for his service under Li Yun.

It is not known when Zheng Changtu was born. His family claimed ancestry from the ruling house of the Spring and Autumn period state Zheng, and a number of chancellors came from the line, including his granduncle Zheng Yuqing and Zheng Yuqing's grandson (Zheng Changtu's second cousin) Zheng Congdang. Zheng Changtu's grandfather Zheng Juzhan (鄭具瞻) served as a county sheriff, while his father Zheng Juan (鄭涓) served as the military governor (Jiedushi) of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi).

As of spring 882, Zheng Changtu was serving as Zhongshu Sheren (中書舍人), a mid-level official at the legislative bureau of government (中書省, Zhongshu Sheng), in the administration of Emperor Xizong, who had fled to Chengdu from the capital Chang'an in light of the attack that the major agrarian rebel Huang Chao launched on Chang'an late in 880. (After Huang took Chang'an, he declared himself emperor of a new state of Qi.) In spring 882, when the senior chancellor Wang Duo was put in overall command of the Tang operations against Huang, Wang retained a large number of imperial officials to serve on his staff, including Zheng, who was made Wang's chief of staff in Wang's capacity as the military governor of Yicheng Circuit (義成, headquartered in modern Anyang, Henan).
