In recent years, with the promotion of social media, "internet celebrity cities" have become a leading indicator of urban cultural tourism. In addition to the well-known popular tourist cities, some second and third tier cities that were once not famous for cultural and tourism have ignited social media with their unique personalities. With the support of traffic, they attract young people from all over the world to visit, and one atypical cultural and tourism "internet celebrity city" after another is widely favored. For example, Shandong Zibo, which has gained popularity through barbecue, has become a "internet celebrity city" driven by traffic and economy due to its "fireworks" of small pancakes and scallions, warm and hospitable attitude, and a strong consumer reputation. For example, Liuzhou, Guangxi, which is famous for Luosifen and Wuling's "magic car", and Jiangmen, Guangdong, which is hot because of the TV series "Crazy Wind", are all representatives of "online celebrity cities". It is worth affirming that the traffic of social media has indeed played an unexpected positive role in the economic recovery of second and third tier cities. Moreover, due to the diverse perspectives of social media, the presentation of urban culture has changed from the template expression of past city promotional videos, which can more move people's hearts. Local governments are also happy to see its success and take the initiative to increase publicity efforts through various channels, striving to maintain the popularity of the city and make "internet celebrity" more than just a temporary sensation. Building a "internet celebrity city" has become a focus of increasing attention from propaganda and cultural and tourism departments. Whether tourists can be retained and how to maintain the vitality of the "internet celebrity city" are important propositions that determine whether the cultural and tourism industry of the "internet celebrity city" can overtake on curves. For cities that have become "internet celebrities", local cultural and tourism promotion departments should not only strive to improve the experience of tourists in terms of food, accommodation, and play, but also consider how to transition from simple "food, accommodation, and travel" to higher levels of "goods, enjoyment, and appreciation". Cities that have not yet become "internet celebrities" should avoid rushing to attract tourists through standardized and homogeneous forms of content. This will not only make it difficult for cities to become "internet celebrities", but will also lose their unique economic development advantages and repeat the repeated construction of "ancient towns" in various regions. Make great efforts in investigation and research, explore the unique characteristics of local culture, and appropriately combine the psychological characteristics of the population and the laws of online communication, in order to attract traffic or be a better choice. However, it should be acknowledged that the rapid updating speed of social media determines the inherent timeliness of "internet celebrities". It is normal for the popularity of "internet celebrity cities" to weaken, and cities do not need to be discouraged by this. It is better to stick to the local characteristics, stick to the service quality, and wait for the next opportunity to follow the trend. After all, the opportunity is always reserved for those who are prepared. The popularity of "online celebrity city" has contingency and inevitable reasons. In fact, whether it's "sunny spring with white snow" or "lowly people", they can all become the explosive points of "internet celebrity cities". Which city doesn't have barbecue? Which city does not have tourist attractions? Which city doesn't have a story? Behind the carnival of traffic, the key to maintaining the vitality of the "internet celebrity city" lies in the cultural connotation that directly points to the soul, breaking away from the expression of outdated thinking constraints, and establishing a high-quality service awareness of seeking novelty and truth. The coming and going of the "internet celebrity city" is worth pondering deeply about the laws behind it. (Wang Wangxin)
