I ask my students that doctors do things neither left nor right, that they should be open to learning from others, but that they should also be critical of new knowledge. The reality is that our doctors, especially our directors, at home, I mean, in the unit, in Ha, show that they know everything, and in front of famous experts in Beijing, Shanghai, etc., they are nothing, they have no problems, they can’t say anything, their hearts are weak. This is very ridiculous, we do not know too much, many famous professors, such as Professor Zhu Yuanjue, said more and more feel will not see; on the other hand, after all, we also work 10 years, 20 years or even more, should have their own things, to express their own views, rather than go to the other extreme, nothing will be. Specifically in learning, Stay hungry, Stay foolish, that is, have a sense of hunger and thirst, and humble, do not preconceptions, “these people lecture, this topic, I will be”, so will not learn knowledge. But on the other hand, don’t accept everything because it’s a famous professor and don’t think about it. We should not be confined by dogma and not live in other people’s ideas. Our education in China is indoctrinated, and as a result, our professors are accustomed to this model, not knowing how to think, not knowing how to accept critically, and therefore, the medical profession is often “the emperor’s new clothes”, as Wang Binbin of Nanjing University said: there are many, many absurd things in the academic world. This habit needs to be changed. This is important, but it is difficult to change without a deep awareness. If the heart changes, the attitude will change, and if the attitude changes, the habit will change, and if the habit changes, the life will change (Gandhi). Jin Chengzhen, Department of Respiratory Medicine, Third Affiliated Hospital of Guizhou Medical University In addition, it needs to be combined with medical history and rich in imagination. Not seeing is believing, but seeing the essence through the phenomenon, or imagining to the essence. You cannot classicize and pattern everything. If you have difficulty in breathing, cannot lie down, and sit up better, you think left heart failure, in fact, COPD patients, even asthma patients are like this in severe cases. When you see a faint white image on CT, you think inflammation, in fact, it can also be scarring; when there is a shadow in the lung field on chest film, you think there is something wrong with the lung, in fact, it can also be on the pleura, imagine that. If you have positive sputum bacteria, you have bacterial infection, cough, fever is bacterial infection, in fact, not necessarily. Be imaginative, dare to doubt, and become habitual so that problems can be easily detected. We should progress in doubt, doubt ourselves academically and doubt whether others are correct. For example, a long time ago, the respiratory community believed that inhaled hormones for 2 years could cure asthma, and I immediately doubted it – that’s habit. The reason was that even if the hormone was anti-inflammatory and the airway inflammation was gone, it would not change his genes, it would not change his allergies, so how could it be cured. Kidney disease is also an inflammatory disease, hormones have an effect on it, can kidney disease be cured? Hardly! Later, I asked the American, and he said he was not sure about this. We academics are sometimes like children, ordinary people, with hot heads! Because not after serious thinking, mechanical and superficial consideration …… Now, it is only said that asthma can be mostly controlled by inhaling hormones. I really hope that our students, doctors, and all walks of life will develop this habit of being middle of the road, imaginative, daring to question authority, and not sticking to the rules ………..
