Jing Kong was a special litigation procedure in Qing dynasty. According to Qing laws, litigations should be handled by Zhou, Xian and Provincial Governments step by step. Should the petitioner skip any step, this kind of action would have been called Yue Su. On contrast, should the petitioner skip any level of the judicial organs of local Zhou, Xian, Dao, or Provincial governments, and appeal directly to Bu Yuan in Beijing, it would have been named as Jing Kong. Different from Hui people of Wai Fan, Hui people of inner provinces were registered in Zhou Xian, and the government kept an eye on this group of people. When in violation of criminal law, they would be more heavily punished than the Hanese. The Jing Kong case of Du Wenxiu was one of the most important made by Hui people in Qing dynasty. During Daoguang period, several fights took place between Hanese and Hui in Boashan County, Yunnan province, and local officials sided with the Hanese. Due to the injustice of addressing the turmoil by the local officials, the Hui people there had no choice but to seek Jing Kong. When the central government accepted the case, the emperor sent Lin Zexu, Governor of Yunnan-Guizhou to handle it. On the basis of the principle "Distinciton between good and evil, no distinction between Hanese and Hui," Lin Zexu dealt with the case impartially and the grievances of the Hui people were temporally addressed. However, the degenerated local governance, and the ethnic discrimination embedded in the local society were revealed with the going on of this case. On the basis of archives of Jun Ji Chu and other original archives of Taipei National Palace Museum, this article gives up the historiography of ethnic oppression, and discusses the social, ethnic, legal problems of border area in Qing dynasty from a new perspective.
