Why is there no outbound tourism statistics on the National Tourism Administration website? If you know it, please tell me, okay?

You need to check it yourself on other networks. In fact, it is quite difficult to count the number of outbound tourists. The country needs to collect inbound travel information for all foreign purposes, and some people may not provide it. For example, in Thailand, you get a visa on arrival, so you can get your passport, buy a plane ticket and leave. Who knows whether you are going to travel or do something else. The same is true for Schengen countries in Europe. If you apply for a country, you can travel to more than 20 other countries. You can travel to more than 20 countries at one time, and you can leave a record of each of these 20 countries. In this way will result in double counting.
