Xi'an has a bewildering array of sights that can confound the visitor with little time to spare. The Terra-Cotta Warriors are a must, as is the Shanxi History Museum, but make sure you also leave time for a walk or bike ride along the city walls, a dumpling banquet, and an alfresco meal of kabobs in the Muslim markets after visiting the Great Mosque.
Eastern Route (Dong Xian) -- Of the two common tours from Xi'an, the Eastern Route is shorter, less expensive, and more popular than the Western Route. There is enough to keep you interested for a whole day, but organized tours of the Eastern Route include "shopping" and sights of dubious merit. While tours are convenient if you have the time, you can do without one. If you are short on time, simply visit Bingmayong as a half-day trip.
