At the entrance of the school and in the supermarket of the community, parents often avoid small packaged snacks such as spicy chips, lollipops, potato chips, and small drinks, but children cannot help but crave them. Half month talk reporters found in interviews that these "price friendly" snack toys for students are becoming a "social currency" for many children, and behind their enthusiasm for "1 yuan" products, there are social needs that they cannot meet. "One yuan" snacks and toys are popular. Ms. Ai, the fourth grade parent of No. 1 Primary School in Xicheng District, Beijing, found a strange thing: her daughter, who never wanted pocket money, started asking for money to buy snacks, and she bought mostly things she didn't eat at ordinary times. Ms. Ai observed at the entrance of the school and found that as soon as school time came, two stationery stores next to the school, with an area of only a few square meters, were crowded with students. Various snacks that were not available during school time were now piled up at the counter of the store. My daughter and several classmates crowded to the counter to grab those "limited time" small packaged snacks. The prices of these snacks are very friendly to elementary school students, ranging from a few cents to a few yuan per bag. After buying snacks and leaving the stationery store, they will exchange with each other. Ms. Zhang, a parent in Shenyang, Liaoning, also has similar troubles. Children like to buy snacks such as spicy noodles, lollipops, and high sugar drinks at the school entrance. Ms. Zhang said, "Although these things may cost a little, eating too much is not good for health. I cannot completely refuse a child's request because their classmates are all eating them, and if they don't eat them, they will be left alone." In addition to cheap snacks, various cheap toys and online games are also the "bonds" that bring friendship closer between children. Outside a primary school in Shanghai, a variety of "five hair snacks" are sold in shops on the street. Wu Zhendong took a half month talk and interviewed reporters. Recently, hand skewers have become popular on campuses across the country. It is often seen that three or five children gather together, holding beads, twisting out sounds, and children say "special decompression". They also compete with each other to determine who has the most diverse bead designs, who has the most distinctive collection of beads, and who is the most skilled at making beads. Xiaolin, a first-year elementary school student, is very fond of Ultraman. Xiaolin said, "Because everyone has Ultraman, I also want to have it, and there are more than them, they will come to me to play." At a birthday party of a sixth grade elementary school classmate, a mother saw that these children were either holding a mobile phone or holding a tablet, in groups of three or five, Formed a "circle of friends" based on the online games you like to play. Behind it lies the psychological needs of children's desire to socialize. Zeng Xiangyun, Deputy Director of the Youth Mental Health Professional Committee of the Liaoning Psychological Counseling Industry Association, analyzed and pointed out that whether it is snacks, bracelets, Ultraman, or online games, they can all be regarded as "social currency", and behind it lies the psychological needs of children's desire to socialize. This is indeed the case in reality. For a small snack, it carries many social functions: expressing intimacy and sharing snacks; Welcome to join and share snacks; Relieve depression and share snacks; Express gratitude and share snacks; You can even play cool tricks and share snacks. ▲ A parent showcases their child at the school entrance for a small supermarket
