1. You can't apply for practicing as a lawyer without pre-job training, so you must attend this training, and I suggest you register for training as soon as possible after you get your internship certificate, so as not to delay your application for practicing. From this perspective, it is very important.
2. The lecturers of trainee lawyer training are generally lawyers who have great influence on the relative business volume of your province or municipality directly under the Central Government, so it is very helpful for you to listen to their lectures.
