Based on the theories of yin and yang, five elements and Chinese medicine, our ancestors divided everything in the world into five substances: gold, wood, water, fire and earth, i.e., any substance in the world can be divided by these five elements. The elements of species both generate and derive from each other, and are mutually exclusive. Of course, the so-called gold, wood, water, fire, earth is only a comprehensive generalization of our ancestors on the world of all things, its gold, wood, water, fire, earth is not just limited to the above simple five substances, and should be made a broad and broad understanding. Five elements are born that gold born of water, water born of wood, wood born of fire, fire born of earth, earth born of gold a cycle, which means: gold can be turned into water, water can nourish trees, trees can be on fire, fire burned out on the generation of the earth, the earth inside the gold; on the contrary, the five elements of each other grams that is the gold grams of wood, wood grams of earth, earth grams of water, water grams of fire, fire grams of gold, and another cycle, which is basically means: the metal material can cut trees, trees can grow in the earth to restrain the earth, the earth can can block the great water, the water in turn can extinguish the fire, and the fire can incinerate and burn the metal into water.

Extended to the theory of Chinese medicine, the ancestors attributed the five organs of the heart, liver, spleen, lungs and kidneys to the five species of gold, wood, water, fire and earth. Namely, the heart corresponds to fire, the liver to wood, the spleen to earth, the lungs to gold, and the kidneys to water. The reason for this is that the characteristics of the five species of gold, wood, water, fire and earth correspond exactly to the characteristics of the five organs, invoking the theory of the five elements of the theory of phases to treat various diseases. Combined with the seven emotions of traditional Chinese medicine, the seven emotions refer to happiness, anger, worry, thoughts, sadness, fear and shock, anger corresponds to the liver, the liver gives birth to fire, so the easiest way to manifest is liver fire, commonly known as the "liver fire" of the body has the following symptoms: dry mouth, bitter taste in the mouth, halitosis, headache, dizziness, dry eyes, sleep is unstable, the body is stuffy and hot, the tongue is coated with thicker fur etc. And what is it that opposes wood? It is gold, and the corresponding organ of gold is the lungs, and the corresponding seven emotions of the lungs are worry and contemplation, the so-called "worry and contemplation". Therefore, when a person is angry and angry, the best way to persuade him is to let the other person think, or let the other person think of something sad, it should be easy to let the other person calm down, at least to stop his anger, in fact, is the theory of traditional Chinese medicine, this is the truth.

Additionally, Chinese medicine uses the term "fire" to describe certain symptoms of heat in the body, and the degree of fire is heavier than "heat". What is generally referred to as fire is the internal heat that occurs when there is an imbalance of yin and yang in the human body.

The Chinese medicine believes that the pathology of "fire" can be divided into two categories, the common symptoms of fire are heart fire and liver fire two.

Symptoms of heart fire and liver fire: heart fire is divided into virtual and real, virtual fire is mainly manifested in heartburn, dry mouth, night sweats, sleep disturbance, etc., drink; real fire is manifested in mouth ulcers, dry mouth, yellow urine, upset and irritability. We often call some easily agitated people "liver fire". In fact, generally known as the "liver fire" of the body and dry mouth, bitter mouth, bad breath, headache, dizziness, dry eyes, sleep instability, body hot, tongue thickening and other symptoms.

So, what you said about why you have to have sores on your mouth and tongue should be the heart fire, not the liver fire.

Finally explain why people will be angry, first of all, people are a very complex organism, and thinking higher organisms, which is the human race is differentiated from other low-level creatures, one of the most essential difference between thinking, thinking, perceiving of course, but also produces the seven emotions and six desires, there are joy, anger, worry, thinking, sadness, fear, surprise; furthermore, from the theory of traditional Chinese medicine, yin and yang, the five elements are Relatively balanced, and is a so-called dynamic balance, in fact, between the five substances are in constant operation and non-stop in the process of transformation of each other's existence, from the point of view of Western medicine, people are subjected to external physical and chemical factors, as well as some of their own bioelectricity and other factors, will lead to the body to secrete a different hormone, in order to mediate between the human body and the nerves, which are the cause of the human body may be angry reasons. .
