The eastern Chinese megacity of Shanghai received a whopping 4.1 million overseas visitors from January to August this year.

The latest tourism boom in the city has resulted from a series of policies that provide greater convenience for international tourists entering China. As one of the country's most famous tourist cities, Shanghai is usually among the first places affected by new policies for the sector.
