Does tourism refer to human activities or phenomena and relationships caused by human activities?

Tourism is a big industry, which affects all aspects. Personal activities in tourism, of course, are tourism, but as far as I am concerned. For example, we always say that Lao Zhang has traveled to Shanghai. Xiao Li has traveled to Nanjing. This is the personal behavior of tourism.

Meanwhile. A person's travel activities. There will be services and economic exchanges in transportation, accommodation, eating, playing, scenic spots and so on. It promoted the development of many industries. This kind of industry that is suitable for personal travel is of course also a tourism industry.

When a person travels to a tourist destination, he will inevitably send money with the tourist destination. The GDP growth of tourist destinations is also a contribution to tourist destinations.

That's it. I hope it helps.
