Signs in Chinese will be set up in publi

问题：

Signs in Chinese will be set up in public areas such as airports, to benefit Chinese travelers, the Italian Government announced in late February. Now many European countries are expected to follow this example.

Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money.

Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid（有效的）in the other European countries. And you can use your mobile phone everywhere.

All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that is more convenient to travel back and forth between the different countries.
