1979 In September, the third Congress of the World Tourism Organization officially designated September 27th as world tourism day. This day was chosen as world tourism day. First of all, the predecessor of the World Tourism Organization, the International Official Tourism Union, adopted the Constitution of the World Tourism Organization at the special congress in Mexico City on 1970. In addition, this day happens to be the handover time just after the peak tourist season in the northern hemisphere and the peak tourist season in the southern hemisphere.
With the rapid development of the world economy and the substantial improvement of people's living standards, tourism has become one of the main choices for people's leisure and vacation. The development of tourism not only provides a lot of employment opportunities for many countries, but also brings them rich foreign exchange income, so governments of various countries pay more and more attention to the development of tourism.
