Comprehensive universities should be an important platform for the development of legal education under their multidisciplinary advantages, nevertheless, the long-term division of disciplines and management mechanisms has become an extreme obstacle to the development of interdisciplinary legal education. How to give full play to the multidisciplinary advantages of comprehensive universities and provide external support for interdisciplinary legal talents has become a crucial issue. Though discriminating the current situation of engineering-law talent training, the deep-seated reasons behind the dilemma of compound talent training are analyzed. Taking civil-law interdisciplinary talents training as an example, the "dual path" compound talent training goal was determined, and the diversion system of learning direction was established. The reform was optimized from the aspects of curriculum system and practical training mode. The "dual path" interdisciplinary zone model was implemented, and good talent training results were achieved. Combined with the exploration of the training mode of "wide caliber" Juris Master education, the research on the training system of civil law was completed.
