A better book to study Neijing professionally?

My friend, there are many books to study Neijing, but don't buy modern textbooks of Chinese medicine. It's all scum. If you have time, you can read more ancient expositions on classics. You can see the concentrated annotation of Huangdi Neijing, the hanging annotation of Huangdi Neijing, the extensive annotation of Huangdi Neijing, the Analects of Confucius and Wu Kun's Wu Annotation of Huangdi Neijing. Now, if you are a beginner, I suggest reading Zhang Jiebin's book. If you want to improve, you can read Zhang Zhicong's book. Su Wen's first 50 explanations are very good, but the explanations related to abdomen theory, strange disease theory and spiritual pivot are still not satisfactory, so I suggest you read Huang Yuanyu's book. In addition, if you study luck, you can refer to Bing Wang, which is very good. Some secret words in Liu's Huangdi Neijing are recognized as the legacy of luck. You put a lot of thoughts on the seven discourses of luck, so that you can understand the contents of the acquired five elements and how to treat diseases with drugs. If you read the first and second chapters of Neijing, go and see Tai Su of Yang Shangshan, but Tai Su has many problems, mainly to improve his understanding of Neijing. I haven't finished reading all these books, but they are precious. After reading them, the theory of typhoid miscellaneous diseases can be skillfully applied. I wish you success if you have a lot of time.
