1. Labor creates people's aesthetic organs. People are evolved from animals. People's feelings have both animal factors and social factors, so should aesthetic feeling. It is precisely because of labor that the human brain can be different from that of apes, and it can have ears that Marx said feel music and eyes that feel formal beauty, and it can have hands that Engels said are engaged in painting, carving and playing the violin. Marx said: "The formation of five senses is the product of previous world history", and the core of this world history is labor history.

2. Labor creates people's aesthetic needs. Primitive humans had no aesthetic needs from the beginning. In the case of extremely low productivity, their most urgent need is to maintain their own material needs. Later, through labor, with the development of productive forces, the improvement of living conditions, and the continuous enrichment of people's essential strength, there were not only material needs, but also spiritual needs and aesthetic needs, so aesthetic feeling came into being. They not only look at the world from a practical point of view, but also feel and appreciate the world from an aesthetic point of view, and constantly establish aesthetic relations with the world around them.

3. Labor creates beautiful things. Primitive people have aesthetic organs and aesthetic needs, and they will consciously or unconsciously create beauty according to the law of beauty in practical activities, such as making labor tools more in line with the requirements of formal beauty from an aesthetic point of view; Claws, teeth and bones are taken from wild animals as decorations to beautify themselves. In practice, they also create works of art such as poetry, songs and dances. In addition, it is precisely because of various practical activities that I constantly improve my understanding and ability to control nature, so that strange and horrible nature becomes close and gradually becomes the object of beauty. In a word, labor is the starting point of human social history, creating people and beauty.
