In recent years, the rapid development of the legal practice teaching system has caused some problems. The huge gap between legal education and the legal profession is a remarkable achievement. In order to solve this problem, the experimental teaching of law must be strengthened. At the same time, under the background of the huge scale of legal education in our country, it is a good choice to effectively carry out legal experiment education and the road of informationization. Follow-up law education should implement the goal of training applied talents. Applied legal talents should not only master a solid legal theoretical foundation, but also have proficient legal practice skills. The application of the emerging legal experimental teaching system LETS system has achieved this goal. However, the application of the LETS system has also made us discover that there are many problems in the current legal practice teaching. The students lack professional legal skills and cannot cope with the solution of actual cases. Students’ legal practice lacks effective guidance, legal business contacts are narrow, legal skills lack comprehensive training, and the evaluation system of legal professional skills training courses is in urgent need of reform. In this regard, we must establish a comprehensive legal professional skills training model and innovate the legal practice teaching system by scientifically and rationally setting up legal practice teaching courses, layering and systematic teaching content, and improving teachers' legal application ability.
