Mathematics video of the first volume of the second day of junior high school
There are indeed many conditions, and the teaching materials of Zhejiang Education Edition are not universal in the whole country, so there are even fewer materials. The materials of mainstream textbooks such as People's Education Edition and Beijing Normal University Edition are easier to find, and there are more and more videos.

In your case, it is almost impossible. Don't lose heart, there are other ways. Is to directly search for topics. For example, the first unit of the first volume of the eighth grade of your textbook is parallel lines, and there is a section about the nature of parallel lines. You can directly search for topics. In Baidu video, after all, junior high school students have learned these things, and there are any versions.

I hope my answer is useful to you.
