Thoughts on loving speed reading and shorthand in Xincheng

I am a student who loves Xincheng. I think the slogan of this course is very good and the editing is very technical, but I think his class is useless. 1 min Read 10000 words, just skim through and remember only a little content. If you want to understand this article, you must read it 3-4 times. In fact, you didn't read it carefully. What he said was that you might as well read it yourself. The eye degree is also long 100 degrees, and he said that playing cards can be taught at home. The above is just a personal opinion, for reference only.
