Things in life, such as food, clothing, housing and transportation, must first meet people's physiological needs, and then we can talk about aesthetics.

At the beginning of mankind, it was difficult to survive even with a warm stomach, so it was difficult to produce aesthetic needs. Only after eating and wearing warm clothes can people gradually have aesthetic needs.

Take China's world-famous cookbooks as an example. They attach great importance to "color, fragrance and shape". Their "fragrance" and "taste" belong to utilitarian physiological needs, while "color" and "shape" belong to aesthetic psychological needs, and "color" ranks first, which shows that China people attach great importance to the aesthetic needs of diet.

But it also developed from the most primitive and unattractive "eating blood and drinking blood".

Even in modern times, when we walk through the wasteland of Lop Nur, the first consideration is nutrition, calories and taste, and we will not put the pursuit of "beauty" first.

All these show that the relationship between aesthetics and practicality is not equal, but there is a first and then, and there is a master and a follower.
