The name Xi'an means "western peace". It got this name during the Ming Dynasty, when the name was changed from Chang'an. These are just two of the many names of the city. It was known as Fenghao during the Zhou Dynasty around 1,046 BC. It was first called Chang'an during the Han Dynasty, around 206 BC. Then it became known as Daxing during the Sui Dynasty, in AD 581.
Xi'an was renamed Chang'an during the Tang Dynasty in AD 618, but was also known by various other names including Fengyuan, Anxi and Jingzhao during the Yuan Dynasty. It has held the name Xi'an from 1369 to 1930, when it was renamed Xijing, but then in 1943 it once again reverted to Xi'an until present day.

Planning your trip to Xi'an
The Xi'an Xianyang International Airport is located some 40 km to the northwest of downtown Xi'an. It gets mostly domestic flights with some international scheduled flights including from Bangkok, Nagoya and Tokyo.
The best way to get out of the city is to take the airport bus, which runs every half an hour and costs ¥ 25 to go to downtown Xi'an, near the Bell Tower, which is right at the center Xi'an. The same journey by taxi will cost ¥ 100.
Exploring Xi'an
Walking may be the best way to see downtown Xi'an. However the Terracotta Warriors are quite a distance from downtown, and should either be reached by bus or a local tour. The local taxi is not a recommended choice, as the drivers have been known to hike up prices for non-locals.
At time of writing (April 2010), a subway is being built in Xi'an but is not yet ready.
