Gulangyu — known as Kulangsu in the local Fujian dialect — is a typical example of this [growing tourism] trend, which has been repeated from Tibet to the Great Wall.
The 2 sq km island just off the thriving port city of Xiamen gets more than 10m visitors a year, almost double the number that visited the entire Philippine archipelago last year. On peak days in the past, more than 100,000 visitors clogged the winding, vehicle-free streets of the island, whose resident population is just 20,000. But the government capped the numbers at 35,000 per day this year as part of the Unesco bid.
