With the rapid development of China’s economy and the continuous transformation and upgrading of its social structure，courts have to handle a pool of litigation cases reflecting complicated social contradictions. The filing and registration system has greatly increased the number of litigation cases，while the quota system for judges has sharply reduced the number of judges who have the qualification for trial. Therefore，during the process of reform，courts are forced to face increasing pressures. As it is impossible to increase the number of judges or to reduce the number of cases by raising the litigation threshold，the reform of sorting between complex and simple legal cases is an important means to effectively relieve this pressure. This paper sorts out the measures taken by Hualong District people’s Court，Puyang City，Henan Province，compares trial quality and efficiency before and after the reform，and explores the problems existing in the work，in order to further explore better measures.
