Zhu Ci
In 782, Zhu Tao, angry that he was not given part of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) after he, pursuant to imperial orders, had participated in the campaign that led to the death of Li Weiyue and had, briefly, returned Chengde to imperial control, rebelled against Emperor Dezong. He went secret letters to Zhu Ci asking Zhu Ci to rebel as well. The letters, however, were intercepted by imperial forces and never reached Zhu Ci. Emperor Dezong, upon reviewing the letters, recalled Zhu Ci to Chang'an and showed him the letters. Zhu, in fear, begged forgiveness. Emperor Dezong responded, "You are thousands of "li" away from each other, and it is clear that you did not join his plot. This is no sin of yours." Despite this assurance, however, Emperor Dezong, while permitting Zhu to retain all of his titles, did not permit him to return to Fengxiang. Instead, he kept Zhu at Chang'an, although he gave him a great mansion, fields, and treasures, hoping to placate him.
