Personally, I think: Chinese medicine is a profound knowledge, which contains thousands of years of human wisdom. If you just know, you can learn slowly through Baidu search. If you want to know more quickly, it is still recommended to use Baidu search, but I don't know to what extent you want to know. Think about it, a knowledge that has gathered the wisdom of various medical schools for thousands of years. If it takes a hundred times the speed, it will take a thousand years, right? Oh, oh, my personal opinion is a bit complicated, but I think if you want to learn well and really understand, let alone practice medicine, you can at least preserve your health for three or two years. As for books, Huangdi Neijing, basic theory of TCM, recipe, treatise on febrile diseases, Hu Ling pulse and so on.
