World-renowned travel website(TripAdvisor)announced that London topped the list of the world’s most popular travel cities in 2016. Besides London’s rich tourist attractions, after the Brexit, the quantitative easing policy was adopted and the rapid depreciation of the pound exchange rate also made London more loved by international tourists. The items evaluated in this survey are the number of website inquiries, the sharing of tourist experience, the number of hotel reservations, and the amount of tourists’ consumption.
