Heart is a commonly used Chinese character, which first appeared in oracle bone inscriptions of the Shang Dynasty. The ancient Chinese character for "heart" represents the heart of a person, bird, or animal, and its original meaning is the heart. The ancients believed that the heart was the organ of thought, so they referred to thoughts and emotions as "heart". It is also extended from the organ of thought to thoughts, ideas, thoughts, emotions, temperament, etc., and further extended to thinking and planning. The heart is located in the central position of the human body, so "heart" has meanings such as central, central, and intermediate parts.
