What to eat:

Yang Rou Pao Mo

what to buy:

Calligraphy Rubbings
Xi'an is a store house of anicent Chinese culture and calligraphy! There are more than 300 steles dating from the Han, Wei, Tang, Song, Yuan, Ming and Qing Dynasties collected in the Forest of Steles in Xi'an. Books of rubbings from some of the most famous Chinese calligraphers can be purchased there. If you are interested in Chinese history, language, or calligraphy, then this is an excellent oppurtunity to enrich your collection of calligraphic rubbings. 

Tang Pottery Replicas
Xi'an's proud tradition as the capital of the Tang Dynasty is kept alive today by modern day replicas of Tang Dynasty pottery. Tang Dynasty pottery, with its distinctive blue, green, and yellow color glazes is still hand-made as it was during the Tang. Common themes include figurines and ceramic camels and horses. Because of this revival in the art of Tang style pottery, buyers should be wary of any shop owners or hawkers that claim their pottery to be "old". Just a reminder! The Tang Dynasty was from about 600 to 900 AD. That would make any genuine Tang Dynasty pieces out of the reach of any ordinary modern day shop.To purchase some Tang pottery replicas, try the Xi'an Friendship Store or Xi'an Cultural Relics Store. 

Mini Terracotta Warriors
Take a Terracotta Warrior home with you! Many different types of replicas are available as souvenirs, from a few inches tall to life-size! Prices range as well, from one US dollar to several thousand dollars for the largest statues. The price of the life-sized statues usually includes shipping to the US or Europe. But buyer beware! The life-sized statues cost a fraction of the price to make, usually less than 400 US dollars. If you take an organized tour to the Terracotta Army site, your tour will probably stop by one of Xi'an's "Terracotta Warrior" factories. You can purchase one there or try the Xi'an Friendship Store.
