How do tourist attractions make money? Thanks

Hello! Domestic tourist attractions mainly make money from tickets, souvenirs, and restaurants, and many of them have government subsidies, because tourism is not just a single industry, it is an industry chain that will drive local economic development. In addition, as visibility increases, We can also host some domestic and international exhibitions, competitions and other activities, such as the various competitions hosted by Hainan every year and the international photography exhibition hosted by Pingyao Ancient City in Shanxi Province... To a certain extent, these are the results of tourism promotion, thank you !
