I suggest reporting to the local graffiti or the Chinese public. They began to have special training courses for police recruitment in politics and law. Because this training institution has a high reputation and a good reputation, and after paying tuition fees, there is generally no extra charge. Moreover, they are nationwide, and most of the internal handouts and materials are completed by doctors and postdoctoral students at the headquarters, which has certain scientific basis.
Why do you need training? I think training is not to learn the right or wrong of certain topics, but to learn the ideas and methods to solve problems, which is the key. Because the topics are ever-changing, but the methods and types remain the same.
Through training, you can meet many like-minded people, including your competitors. You can see how others learn, and how you learn, and learn and grow by comparison.
