Food and clothing are solved, and life is comfortable. Naturally, I hope to live a long and healthy life, so that I can fully contribute to society and enjoy life leisurely. The actual demand of people and the promotion of the market have created a hot situation of health care books. So many health experts suddenly appeared in life. Many friends want to have a practical health book at hand, but when they walk into the bookstore, they often find it difficult to choose among all kinds of health books. The author is a clinical worker, keen on medical science popularization, has compiled and published several health care pamphlets, and usually likes to visit bookstores and buy some books. Here, combining my personal understanding of health preservation and my experience in buying books, I will briefly talk about my experience in buying such books for your reference. One depends on the author. There is no denying that many folk health experts have mastered a lot of health experience from practice, but health is a kind of specialized knowledge after all, involving a wide range of medical knowledge, so the author's academic background is very important. Whether it is Chinese medicine or western medicine, it is best for the author to graduate from a regular medical college and work in a regular medical institution, medical college or scientific research institute, and it is best to have long-term clinical work experience. A master painter may have different views on health care, but as an amateur author, it takes a lot of effort to write a systematic and practical health care book, so the chances that amateurs can successfully write such a book are very low. Therefore, it is very important to know the author's academic background. If you have time, you can search online. If we can use China HowNet, VIP information and other professional retrieval systems, it will be more telling. Second, it depends on the publishing house. There are corresponding authoritative publishing institutions in many fields, such as People's Literature Publishing House and Writers Publishing House, and other fields include Education Publishing House, Chemical Industry Publishing House and Foreign Language Teaching and Research Publishing House. For health care, books published by professional publishing institutions such as People's Health Publishing House, People's Military Medical Publishing House, Science Publishing House and Science and Technology Publishing House should be selected. The author has written several health-preserving pamphlets, such as Looking at the Tongue to Differentiate Diseases and Keeping Healthy, and Classic of TCM Health-preserving, all of which were published in Shandong Science and Technology Publishing House, while the Manual of Health Examination was published in People's Military Medical Publishing House. These publishing houses were established earlier, with standardized operation, high professional quality of editors and generally guaranteed book quality. Third, you should choose a chapter that you are most familiar with or interested in, and judge the quality of the book from your existing knowledge and experience. If it meets your own taste and you can't pick out the flaws in the knowledge points, it is basically acceptable. If you find that the knowledge introduced is wrong or not suitable for your taste, you should seriously consider whether to buy it. Fourthly, the author's writing style and book binding design. Although binding design is very important, it is only equivalent to one person's clothes. Don't judge a book by its cover. Writing is also very important. The best popular science works should accurately convey correct scientific knowledge in simple and interesting language, but the most important thing is whether the knowledge points are correct. Just like a person with a good eloquence, there is no need to listen to what he says, even if he is eloquent and spits lotus flowers, or he is just talking nonsense. Having said so much nonsense, I certainly hope you can buy a high-quality health care book that suits you. Of course, it's mainly up to you. I wish you the best of health!
