MICE tourism should also choose a distinctive theme to provide more professional tourists and potential customers for MICE through its strong attraction. Similarly, exhibitions can also bring more tourists to the host city by holding exhibitions with strong brands. Choose theme exhibitions related to urban tourism resources and characteristics, so that exhibitions and tourism can play their respective advantages and develop interactively. As we all know, the Kunming World Expo in Yunnan has had a wide and profound impact on its urban tourism and exhibition tourism. The research shows that 1999 World Expo has promoted the status of Kunming tourism in the whole province and even the whole country, and promoted the branding process of Kunming tourism destination, which is one of the major events in the history of mice tourism development in China.

Drawing lessons from the successful experience of Kunming, Changsha should start with large-scale exhibitions such as Golden Eagle TV Art Festival, Liuyang International Fireworks Festival, National Sugar and Wine Fair and Provincial Agricultural Fair, and try to combine theme exhibition activities with theme tourism to tap the market depth. For example, Golden Eagle TV Art Festival and film and television tourism products, the establishment of film and television art center, the display of China film and television art and culture, Liuyang International Fireworks Festival tourism and local tourism resources, the development of eco-tourism, in the national sugar and wine party, the provincial agricultural fair, tea culture festival exhibition, emphasizing Hunan's unique tourism resources (such as Li Baixing Shacha Gallery, Changsha Baisha Gujing, Ningxiang tourism resources), combined with leisure tourism, rural tourism, so that traditional wine culture, rural tourism. For example, Martyrs Park in Changsha is one of the top ten parks in China. Martyrs Park attracts nearly 4 million visitors every year, and successfully holds light shows and auto shows every year, with more than 300,000 visitors each time. Changsha is trying to build an "ecological, cultural, scientific and modern garden" with Martyrs Park in two years, so that tourists can appreciate the beauty of Martyrs Park and feel the charm of Changsha International Ecological Exhibition. This way of thinking fully integrates exhibition and tourism, which greatly promotes the development of both.

Tourism has a powerful driving force for gathering popularity, prospering the market, stimulating consumption and promoting investment attraction, which is a key link in Changsha's economic development strategy. Compared with other famous tourist cities, there is a big gap in the proportion of tourism in the tertiary industry in Changsha. Therefore, the only way to inject new vitality into Changsha's economy is to integrate tourism resources, speed up the development and construction of tourism industry, cultivate and develop a new tourism market-mice tourism, build a tourism network that runs through both inside and outside, and build an overall brand with strong Huxiang culture and distinctive Changsha characteristics.

Hainan has also done a good job in this respect, and there are many exhibition tourism projects, such as Hainan Island Happy Festival, Fairy Lady Culture Festival, Wanning Lantern Festival, Hainan Tropical Rainforest Festival, Nanshan Longevity Culture Festival, Sanya International Beer Festival, Sanya International Advertising TV Art Festival, Tianya Haijiao International Wedding Festival, Baoting Qixian Hot Spring Swimming Festival and so on.
