According to reports from Chongqing on May 29th, another Children's Day is approaching. While children are still preparing seriously in the classroom for cultural performances, adults have gone crazy online to "show childhood photos". Sandbags, shuttlecocks, rubber bands; white shirts, blue pants, red scarves... these nouns deeply imprinted in the hearts of post-70s are repeatedly mentioned on various websites, forums, and shopping websites. It seems that children have been overshadowed by adults. Whose show is Children's Day anyway? Personal memories, proof of growth. Recently, social networking sites such as Kaixin.com launched a main theme activity titled "Upload Childhood Photos, Recall Happy Childhood", with over 600,000 users participating in the group reminiscence of childhood, uploading more than 300,000 photos. Some celebrities also posted their childhood photos via microblogging to share their childhood fun. The reporter noticed that childhood photos are just one of many items witnessing growth and breeding nostalgia. Many young people with business minds have already turned nostalgic feelings into tangible commodities. Li Xin, born in 1980, now runs a personalized store in Beijing. The store is less than 20 square meters, almost unrenovated, with an unusable 14-inch black-and-white TV placed inconspicuously in the corner. The main products sold include Huili shoes, sailor shirts, enamel mugs, tinplate toys, and other items with obvious marks of the 1980s. He introduced that despite the prices of these items being several times higher than before, they still sell well, with daily turnover averaging between 2000 to 3000 yuan. The customers are mainly students and white-collar workers, most of whom are also post-80s. When asked why these items are so popular, Li Xin answered: "These things represent the beautiful times of the past for them. Once they see them, they associate them with their own stories, naturally feeling close." Zhong Cheng, born in 1985, is enthusiastic about these items, liking to wear Huili shoes, sailor shirts, and tight pants, considered a "fashionable man" and "artistic youth" in the eyes of many. He frankly admitted that these "old goods" actually represent a lifestyle, simple, practical, not flashy, but full of creativity, with eternal value. "I have been playing soccer in white Huili shoes since I was a child, and if they got dirty, I would just use chalk to paint them. You can say it has grown up with me, accompanying my growth." Urban memories, symbols of development. As generation after generation grows up, the cities where people live are developing simultaneously. Growth has memories, and the development of cities also has memories. Many people have watched the movie "Crazy Stone" and were deeply impressed by the cable car crossing Jialing River shown in the film. On March 1st this year, due to conflicts with the plans of two newly built bridges, the cable car officially stopped operation, and many people rushed to take the last ride, both to bid farewell to it and to witness their common growth with the city. The Jialing River Cable Car in Chongqing was built in 1982, connecting Yuzhong District and Jiangbei City. It is 740 meters long, with a maximum capacity of 46 people per carriage, making it China's first urban river-crossing passenger cable car and one of the most representative urban symbols of Chongqing. In January 2010, it was listed as a municipal-level cultural relic in Chongqing. Citizen Li Zhiming, 55 years old, lives in Yuzhong District and works in Jiangbei. He told reporters: "I have always taken the cable car to and from work, for 29 years, never thought it would retire before me... Now every day I can only squeeze onto the bus." Sun Li, 25 years old, has deep feelings for the Jialing River Cable Car. He said: "When I was a child, every time I went to my grandmother's house, I would take the cable car. I liked playing in the box behind the chair the most; after growing up, after my first date with my first girlfriend, I also took the cable car home... This cable car carries too many of my memories, you could say it witnessed my growth, and also witnessed the growth of Chongqing." Besides the Jialing River Cable Car, the citizens of Chongqing also bid farewell to an old friend - the Shapingba train station which had been operating for over 30 years - on May 8th this year. The Shapingba train station was built in 1979 and was once the starting station for direct trains from Chongqing to Beijing, Zhengzhou, Wuchang, and other places, sending out up to ten thousand passengers daily, with an annual total of 1.2 million passengers. Later, due to the construction of Longtousi train station, most of its services were diverted. In 2010, the passenger volume was only 250,000, leaving only the trains from Chongqing to Nanchong, Sichuan, and Chongqing to Zhaotong, Yunnan, along with some staff commuting trains, all green-skinned trains. This year, Chengdu Railway Bureau decided to close down for renovation and transform the Shapingba train station, which will primarily stop at Chengyu high-speed rail trains in the future. Ms. Zhang, living in Yubei District, specially bought a ticket in advance for the train from Chongqing to Beibei, costing 4.5 yuan, just to bid farewell to the Shapingba train station and experience the last trip of the "green-skinned train". She said: "I spent dozens of yuan taking a taxi to the station, not for anything else, but to find the feeling of going home back then. I attended university in Beijing back then, and I used to take the train from Shapingba. Every time I returned to Chongqing on vacation and saw the Shapingba station, I was particularly excited because I was home." Collective nostalgia, spiritual attachment. From individuals to cities, from "Old Boy," Huili shoes, to Jialing River Cable Car, Shapingba train station, these things, apart from having specific era values, carry more value in the collective memories of a generation and a city, witnessing personal growth and urban changes. In recent years, with the acceleration of urbanization, adults' nostalgic feelings have become increasingly intense. After old city renovations, some adults even miss the snack stalls that have been in front of their homes for decades, reminisce about the green mailboxes at certain street corners, or even the "Pechoin" cream their mothers once used. Yang Dong, director of the Applied Psychology Department at Southwest University's Psychological College, said from a psychological perspective that during the process of growth, people have profound impressions of many beautiful things that brought happiness in their childhood. After adulthood, the pressures of work and life, along with dissatisfaction with the current situation, gradually drive away those beautiful feelings. "Nostalgia" is not only about missing past things but also about searching for those once-beautiful feelings again." Yang Dong said.
