In recent years, more and more cultural and Expo venues and public cultural places have become gathering places for young people to socialize and punch in. According to relevant data, from January to May this year, among the most popular scenic spots in China, museums and exhibition halls ranked first. Among the tourists who made reservations to visit the museum, the youth group accounted for the highest proportion. On the social platform, the number of content related to cultural and Expo venues is increasing day by day, and the popularity of cultural and Expo tourism is comparable to the "top stream". Why are cultural and Expo venues represented by museums more and more popular with young people? Why is the social attribute of cultural and Expo tourism increasingly prominent? From the perspective of culture, the long-standing traditional culture and the future oriented innovation concept have created common prosperity in the symbiosis. From the documentary "I build cultural relics in the Forbidden City", to the variety show "national treasures", to "Tang Palace Banquet" and "just this green" and other literary and artistic works, cultural content related to culture and Museum has repeatedly "broken the circle" with innovative forms of expression, which has attracted the attention and love of young people. At the same time, in the process of strengthening the protection and utilization of cultural relics and the protection and inheritance of cultural heritage, the operators of cultural and Expo venues around the country have tried to make cultural relics "live" with innovative means, opened up "cross-border" cooperation between cultural and Expo IP and blind boxes, cosmetics, catering and other fields, and integrated traditional culture into the daily lives of young people, resulting in a series of topical cultural and Expo related content, Constantly bring innovative cultural experience with novelty to young people. In order to better meet the spiritual and cultural needs of the people, today's cultural and Expo venues are no longer limited to cultural relics display, cultural explanation and other functions. With the development of industry and the progress of science and technology, the cultural and Expo venues not only have a higher and higher overall "appearance", but also expand more fields such as immersion experience, leisure and entertainment, cultural and creative consumption offline, providing a broad space for young people to socialize and punch in. Online, digital channels such as the "digital Forbidden City" applet released by the Palace Museum and various social platforms and cultural and Expo related topic areas not only enable people to "visit the cloud" and "interact with the cloud" without leaving home, but also provide more possibilities for the visually impaired and the elderly, and build a cultural and Expo online community for young people to share and communicate. We are happy to see that the cultural and Expo venues represented by museums are becoming more and more "hot", and traditional culture and ancient cultural relics are becoming more and more "alive". However, the hot content of young people's social networking and clock in is often the fashion for a period of time, and there is a phenomenon of rapid change. How to make cultural and Expo tourism not only a temporary hot spot, but also a "top stream" for a long time, so as to gain the continuous recognition of more young people, is a problem that all parties must consider. On the one hand, we should keep pace with the times and improve the systematic development of the cultural and museum industry. It should be noted that young people are the most innovative group, and the development of the cultural and Expo industry is not limited to one generation of young people. On the premise of taking root in the broad and profound connotation of traditional culture, we must combine digital means, develop diversified businesses, improve comprehensive operation ability, and solidly promote the overall development of the industrial chain, so as to gain recognition in the common growth with generations of young people. Local cultural and Expo industries should also adapt to local conditions, find their own development path, highlight distinctive features, adhere to the awareness of high-quality products, maintain iterative updating, and attract more young people through high-quality differentiated content. On the other hand, we should focus on the key point of taking people as the core. Based on the needs of the audience, including young people, all parties should continue to create cultural and Expo content with communication, participation and interactivity; We should also cultivate and tap more special talents to integrate more innovative ideas into traditional culture. After all, the reason why young people make cultural and Expo tours in the circle of friends is to establish a sense of resonance between people. Only when there is someone in mind, can they have an insight into what people want, so as to launch more and better content. Those cultural treasures that have gone through thousands of years have also been "young", and it is through the protection and love of young people from generation to generation that they can be inherited to this day. The impetuous, shallow, good-looking and interesting can only bring a temporary sense of freshness. Only the long-lasting cultural connotation can truly impress the young people of every era and make the cultural and Expo tour a "youth journey" across time and space. (outlook new era)
