Traveling everywhere is on foot. Why do you call it?

Tourists walk, swim and watch, regardless of time and season, and are carefree. It is very popular in western developed countries. Especially in the Federal Republic of Germany, "Volks hiking" (German "Volks" means "people" and "nationals") has almost become a national activity. According to statistics, there were 24,000 participants in China from 65,438 to 0968, and the number soared to 7 million from 65,438 to 0977, accounting for more than 1/9 of the total population. This kind of mass tourism activity usually starts on weekends, ranging from10 km to 40 km, with self-control speed; Some people also use their holidays for long-distance hiking, such as going to the beautiful Alps, and even going to places of interest or rural towns in neighboring countries such as Denmark and Luxembourg. At present, this kind of tourism has spread to other European countries.
