After seeing this question, I opened the Driving Test Booklet again and looked at it. It turns out that it has been revised, especially the community page has changed a lot. It has become an information flow format similar to Xiao's book, which looks more intuitive, and according to the bulletin, the content seems to be richer. There are topics that can be directly interacted with, and there are also pictures or videos. It feels like it is completely in line with the user's browsing preferences. The revisions made are pretty good.
