Professor Luo Zheng from the Department of Psychology of Peking University analyzed that women's skirts and men's short hair have become their secondary sexual characteristics besides the most typical physiological characteristics of sexual organs. Men with long hair are actually challenging traditional social rules and mainstream culture, and this group of hidden people are willing to show their personalities.

When a certain impulse and demand in human heart is suppressed, this impulse slowly penetrates into the subconscious. Maybe he didn't know that he had the purpose of challenging the secular vision, but it was fully revealed at the subconscious level. Maybe they don't admit or even realize that long hair is a challenge to society, but their long hair secretly reveals secrets.

Male long hair is the expression that modern people pay more attention to perceptual desire.

Until now, when it comes to long hair, people will think of "artists" first, because the first men who have long hair are often singers and painters. "This is related to the emphasis on' body' in modern society." Dr. Bao, an associate professor in the Chinese Department of Nanjing University and a tutor for master students, specially studied contemporary singers and reinterpreted the "body" phenomenon in today's concerts. He believes: "Modern society is an emotional society. One of the main characteristics of modernity is to liberate people's perceptual desires and pay attention to secular life. Before the17th century to19th century, the traditional theory also divided the body into two parts, the one above the neck belongs to the mind, and the one below the neck belongs to the body, which set the body and the heart against each other. " "It is precisely because modern people, especially young people, pay attention to feeling and body, so even in concerts, we should highlight the element of' seeing'. This also explains to some extent why young people nowadays don't like Chinese music and Beijing opera. "

"The release and expression of' body' is nothing more than the following body components: hairstyle, clothing, body, body movements and sound. As a cultural symbol, hairstyle has important symbolic significance. "

Long hair can flutter in the singer's singing process and become an extension of body language, which meets the social and psychological needs of the audience, that is, young people who have long hair later pay attention to the body and are more willing to pay attention to the emotional level, so long hair has been preserved as a cultural symbol.
