Analysis: I got a securities license and bought two of them. One of them is almost finished, and the writing is too poor. Just now I called Tian Ming Education and said I couldn't get through!

The author's Chinese is really poor. Words with the same meaning should be separated, and words that should not be put together should be put together. The title doesn't correspond to the following content at all.

The second is that the content is too verbose. A noun can list six names, but I don't know how to get rid of those names that are already useless. There's no point!

I didn't know there were official books, otherwise I would never buy such books!
