How much time does continuing education need to spend reading books and then taking exams every year?

For example, in Jiangsu, you have to read books on the prescribed website 24 hours a year, and then pass the prescribed examination before you can pass the continuing education.

However, in some special circumstances, such as the accounting knowledge contest and the law popularization contest, as long as you take part in such activities, even if you study for many hours, it can be regarded as continuing education. You can take so many hours less classes next year, and the rest is almost the same.
