What are the seven emotions in China's ancient books?

The seven emotions are joy, anger, worry, thinking, sadness, fear and surprise. The seven emotions are closely related to the functional activities of zang-fu organs. The seven emotions belong to the five internal organs, represented by joy, anger, thinking, sadness and fear, and are called "five aspirations". The seven emotions are different reflections of the human body on external objective things, and are normal phenomena of life activities, which will not make people sick. However, under the sudden, intense or long-term emotional stimulation, it is beyond the normal range of physiological activities, but it can not adapt, which will lead to the disorder of qi and blood function of zang-fu organs, thus leading to the occurrence of diseases. At this time, the seven emotions become the pathogenic factor and one of the main factors leading to internal injuries, so it is called the seven emotions of internal injuries. As a pathogenic factor, the seven emotions, different from the evil of six evils, enter the human body through the nose, mouth and fur, but directly act on the related viscera and cause disease. Emotional factors can not only directly lead to the occurrence of various diseases, but also play an important role in the prognosis of all diseases.
