I recommend Shuoning Education to you, because I have personally participated in it, so I tell you that as we all know, English includes listening, speaking, reading and writing. As far as listening is concerned, Shuo Ning first trains your English thinking, including phrase thinking, because English is mostly a string of phrases, not a single word. This training method has an original principle called RUN principle, which is repetition, understanding, narrow listening and repetition. Understanding means that you have to understand more than 85% of these contents. Narrow sense of listening refers to including keywords and keywords, which can remind you of the main content of explanation. Use it again and again, and you will gradually improve. This is only part of it. If you are interested, you can continue to ask.
