In 166, a major public confrontation between university students and eunuchs evolved into a major incident. The governor of the capital province (modern western Henan and central Shaanxi), Li Ying, had arrested and executed a fortuneteller named Zhang Cheng (), who had had his son kill a man, having predicted that a general pardon was coming. Li was arrested and 200 some university students signed a petition requesting his release. This further angered Emperor Huan, who had the students arrested. Only after about a year and Dou Wu's intercession were Li and the university students released, but all of them had their citizenship rights stripped. This incident was later known as the first Disaster of Partisan Prohibition.
