What technology does the domestic tourism website system use?

China's tourism website system uses programming language.

To understand the programming language, most travel websites use PHP, and travel cms can be used to build them, which is fast and worry-free, and the websites made are also beautiful. The idea belongs to the tourism CMS that can be developed twice, using PHP+MySQL language, open source without encryption,

If you do other websites first in the future, you can save the cost of building a website.
