World Smile Day investigates the facial expressions of pedestrians in Nanjing-Yesterday was a warm day-"World Smile Day". "Did your mouth increase by 15 degrees today?" Yesterday, as of 9: 00 p.m., the discussion on Smile Day on Sina Weibo had exceeded 2 1 10,000 times, and this slogan had the highest citation rate. At 3 pm on the 8th, the reporter conducted a street survey at the exit of the underground passage at the intersection of Hanzhong Road and Guanjiaqiao Road in Nanjing. In about 10 minutes, 50 pedestrians passed by, most of them men. According to the reporter's observation, only four people are smiling, and these four people are still two pairs of friends and colleagues. Among other pedestrians who "act alone", five people are talking on their mobile phones. A man shouted "Hello, Manager Li ……" and hurried by, staring at the screen of the mobile phone and texting. There are also three people listening to music with headphones. Others stare at the ground, browse the street view, and look serious or frown slightly. Obviously, on World Smile Day, few people can give themselves a smile. "Smiling is not something you can get by going to comedies and entertainment places." Wang Lanfang, an associate professor of sociology at Nanjing University of Science and Technology, believes that "laughter" obtained through entertainment and consumption is not real laughter. Smile is a spiritual word. It is not only a symbolic expression on the face, but also represents a person's friendliness to others and the world. The condition of smiling is firstly the warmth of the soul, followed by the return of the soul and inner peace. In contemporary society, the pace of life and work is getting faster and faster, the competition is more intense, and people's anxiety is increasing day by day. In this case, the significance of World Smile Day is even more prominent. It reminds people to pay attention to their inner and spiritual world. "Laughter and laughter are actually two concepts. Laughter doesn't necessarily convey happiness, but it may also convey emotions such as embarrassment, anger and sadness, and a smile must convey positive energy. People get along with each other like a mirror, and all kinds of emotions you put in will be reflected through each other's faces. Why are the foreign teachers around us always happy? They don't care about their smiles. Regardless of whether the people coming from the opposite side know it or not, they are used to smiling and greeting, so that positive energy can infect others. " Cai Yuan, a psychology teacher at Nanjing Audit University, said. "In the west, when two strangers look at each other, if one of them smiles, the other will respond with a smile. People in China will laugh when they meet acquaintances, but not necessarily between strangers. From a sociological point of view, the etiquette communication model and culture between strangers have not yet been established, so it is understandable that passers-by reject, alienate and be indifferent to strangers' smiles. " Yang Guangfei, a sociology professor at Nanjing Normal University, said frankly. Someone once lamented that "China people can't laugh". Real life does give people this feeling for many reasons, such as stressful life and work, depressed interpersonal environment, etc ... but this should not be the reason to stop smiling. "In an impetuous and chaotic society, most members of society can't get rid of the influence of utilitarian heart. If people want to restore their smiles, not only by economic means, we should start from the whole society and create an atmosphere that can make people feel at home. Moreover, a smile can't be solved by one person in society. Life and quality of life are all your own, and your heart is your own. Personally, everyone should seek spiritual self-help through self-study. Associate Professor Wang Lanfang said. Maybe we can't change our interpersonal environment, the pressure of work and survival, but we can at least change our expression. Let every day be a smile day, have a happy personality, and every day is a smile day. The beauty of the whole world may begin with your smile. Our reporter Ge Lingdan Ji Zhu Feng Sun Qing
