Footloose in Xi'an: More than the terracotta army

XI'AN, China -- Say the word Xi'an, and people think of the Chinese city's astounding collection of terracotta warriors, created to guard the Emperor Qin Shi Huang's tomb in the third century B.C. But on a recent trip to the city, the capital of Shaanxi province, I discovered that there is much more to see -- from a well-preserved city wall to quirky pagodas, lively markets and a thriving street food scene.
