Hello, the reason for the error at the end of the fast-forward learning video of continuing education is that the platform will have irregular operation detection. In this case, the double-speed learning time will be cleared. Because accelerating the development of the continuing education system will cause problems with the integral function of the system. After all, continuing education is an educational activity for people in the workplace and an opportunity to improve their abilities. Of course, if we participate reasonably and legally and adopt correct learning methods and means, we can not only shorten the training time, but also learn more knowledge and skills. Those who need to study law can discuss it, and you can test whether my method is efficient.
