Cui Rongrong's English grammar video is a classic introductory course of English grammar, which is taught by Cui Rongrong. The course is very good. As long as you listen to this course carefully, your English grammar will be fine. I suggest you study step by step and don't rush it. Listen to one lecture, and then listen to the next one after practice. I hope everyone can learn to consolidate the basic knowledge of English grammar and lay a solid foundation for learning and mastering more English knowledge.
