Doubt, that is, the meaning of doubt, to learn to learn to "doubt" in the study of Chinese medicine, that is, there must always be doubts in the mind.
Why is "wetness trending down"?
Why "Wet Air Blocker"?
Why "wet turbidity"?
In the process of "seeking", we should ask more why
There are many questions that are not answered in textbooks, which requires us to think more and think more.
When a myriad of questions pop up in your mind, you will unconsciously begin to search for answers. This process of exploration is like an endless adventure, you keep digging and exploring, just to find that glimmer of truth. In the process, you will not only gain a wealth of knowledge, but also go further and further on the road of knowledge. When we were younger, we were always full of curiosity and questions about the world. Those strange questions, like stars in the night sky, light up the path of our growth. As the years go by, we gradually form our own worldview and begin to interpret the world with our own eyes. As a result, those doubts that once troubled us seem to gradually disappear in the trajectory of growth. However, the reduction in doubts does not mean that we are really mature. On the contrary, it may mean that we are less sensitive to the world and that we are getting used to seeing things in a fixed way. In the process of learning TCM, we should keep a curious heart and constantly ask questions, only in this way can we truly study in depth and truly understand the essence of TCM. When you encounter a problem and can't figure it out, don't give up easily. Put this question between heaven and earth and let it talk to nature. Because in the lap of nature, many mysteries will be solved. Therefore, let us move forward with doubts on the road of traditional Chinese medicine, so that every exploration can become a boost for our growth. 
Here's an example of the beauty of being "suspicious".
When I was studying the Neijing, I was always confused about the understanding of the phrase "Yang in spring and summer, and Yin in autumn and winter". If the summer is hot, it stands to reason that yin should be nourished, while autumn and winter are cold, yang should be nourished. What exactly does "raising" mean in this?I consulted a lot of information and found that the doctors and schools of thought had their own interpretations, which made me even more confused. By chance, I found the answer. That summer, I went to a cave to play. Despite the heat outside, as soon as you enter the cave, you can feel a sense of coolness. I carefully observed the environment of the cave and found that the cave was very humid, and the water vapor from the roof of the cave would drip from time to time. I learned about the cave's warm winter and cool summer, but I didn't care about it before. However, after learning the "Neijing" "spring and summer to raise yang, autumn and winter to raise yin", I suddenly understood the deep meaning of this sentence. In the summer, although the weather is hot, the cave is cool and humid;In winter, although there is heavy snow outside, the inside of the cave is warm and dry. This is exactly what I have read in books before. The human body, like the natural world, has strong yang energy on the surface of the body in summer, but lacks yang energy and is moist in the body;In winter, Yang Qi is stored inside, and the human body is prone to deplete Yin fluid, resulting in dryness. So, since spring and summer are yang, why do people like to eat sorbet in summer?And you will feel comfortable after eating?Is this contrary to the principle of raising yang in spring and summer?In fact, eating cold food does not violate the principle of spring and summer yang. Because people eat cold food in summer, mainly to cool down and regulate the balance of yin and yang in the body. However, if you eat too much cold food, it will cause too much cold in the body, which will affect the growth of yang energy, which will affect the health of the body. Therefore, in the process of raising yang in summer, we need to pay attention to moderate diet adjustment and avoid excessive consumption of cold food. In our natural world, the sun is like the heart of the human body, providing a constant source of life energy. The atmosphere is like our lungs, helping us breathe and absorb the oxygen we need. The land is like a human spleen and stomach, providing us with abundant nutrients. The mineral deposits and water sources beneath the earth, like our kidneys, are responsible for purifying the body and eliminating toxins. In summer, the air above the ground is hot, but inside the cave is cool. This is just like our body in spring and summer, the heart and lungs are vigorous, but the spleen and stomach are relatively deficient. Therefore, in spring and summer, we need to raise the yang of the spleen and kidney, not the yang of the heart and lungs. In autumn and winter, the temperature gradually decreases, and the yin of the five internal organs needs to be nourished. For those who haven't visited a cave before, try the well water. The well water also has the characteristics of being warm in winter and cool in summer, which is quite similar to the temperature change in the cave. With this in mind, let's look at patients with rheumatism and gastrointestinal diseases in clinical practice. Spring and summer are the peak periods for these diseases. In these diseases, we use warm medications such as aconite and aconite. Every spring and summer, I use a large amount of aconite and aconite, and the total amount even reaches hundreds of kilograms. In autumn and winter, despite the cold weather, most patients have a deficit in their body, so the opportunity to use aconite is relatively reduced. The process of learning Chinese medicine is a process of constantly questioning, thinking, and solving doubts. Only by maintaining the exploration and curiosity of knowledge can we gradually unravel the doubts in our minds. When one day, these doubts are suddenly solved, we will experience the joy of sudden enlightenment. This process from "doubt" to "enlightenment" is not only exciting, but also the best reward for the pursuit and exploration of knowledge and wisdom.
