For the first time, the relationship between music and speech was mentioned, believing that music is the continuation, processing and extension of speech; singing originated from people's need to fully express their thoughts and feelings. Ancient Chinese Confucian music aesthetics - the idea of ??ritual music, has evolved to the "Book of Rites? 6? 1 Music Notes" and has reached its limit. Since the Han Dynasty, although it has continued continuously, most of them have basically stagnated due to changes in time and have rarely developed. In the pre-Qin period, thinkers who held opposing views to Confucian etiquette and music thought mainly included Mozi (about 480-420 BC), Laozi (who was born and died slightly earlier than Confucius) and Zhuangzi (about 355-275 BC). . Mozi wrote the chapter "Feiyue". From the narrow standpoint of a small producer, he believed that music was a waste of manpower and financial resources and hindered production, and he strongly opposed it (see "Mozi? 6.1 Feiyue"). The ideal of Laozi and Zhuangzi is to return to the original state of mankind, that is, the world of "perfect virtue". They believe that in that era of supreme virtue, the people were simple in nature, without rituals and music, and there was no distinction between gentlemen and villains. When rituals and music came into being, antagonism arose in the world, people began to have a fighting spirit, and the original simple beauty of the world was destroyed. Zhuangzi's thought is against artificiality, and therefore denies ritual and music. On the other hand, Laozi and Zhuangzi are people who understand the laws of music and art. Lao Tzu talked about "big sounds are like sounds", and also said: "Existence and non-existence arise from each other, difficulty and ease complement each other, long and short complement each other, high and low lean towards each other, sounds harmonize with each other, and follow each other before and after." Zhuangzi said that "the ultimate happiness is without happiness", and he described The entire universe and the movement of celestial bodies are seen as the most perfect and harmonious silent music. Zhuangzi believes that the laws of music and the laws of nature in the universe are connected and consistent. Nature itself contains many factors found in music, such as rhythm, rhythm, regularity, harmony, etc. Therefore, in Zhuangzi's view: music is also created based on nature, and the blueprint must be better than the model, the beauty of nature must be better than the beauty of man, so silent music must be higher than sound music. This is probably the meaning of "pure happiness without happiness".
