In 2020，the COVID-19 epidemic has an extensive impact on the tourism market of the Guangdong-Hong Kong-Macao Greater Bay Area. Tourism in the Greater Bay Area has undergone a process of anti-epidemic，recovery，and adjustment. In the early stage of the epidemic，the number of tourists in the Greater Bay Area fell precipitously. Scenic spots，hotels，and other densely populated places were closed. And a large number of tourism companies were struggling to operate under the epidemic. The government actively introduced financial support，tax incentives，rent reductions，and other relief policies to help the tourism industry tide over the difficulties. After the epidemic was brought under control，the tourism market in the Guangdong-Hong Kong-Macao Greater Bay Area slowly recovered. Relevant companies actively cooperate with the epidemic prevention and control work. Among them，the implementation of measures such as online appointments and contactless services have promoted the smart transformation of the tourism industry in the Greater Bay Area. The epidemic has also changed the behavior of tourists. Road trip in the province with friends and relatives has become a trend. Tourism products such as red tourism，educational tourism，night tourism，and immersive experience are also popular among tourists. In the future，the Guangdong-Hong Kong-Macao Greater Bay Area will improve the quality of tourism products and services by the guidelines of the “14th Five-Year Plan”，while also focusing on epidemic prevention and control and market supervision，creating a safe and quality consumption environment，and creating a world-class tourist destination.
