Ya'an is a refreshing mixture of Han Chinese tradition and modern Chinese peasant culture, with a dash of Tibetan influence.[...]Near Ya'an a monument once marked the traditional border between China and Tibet. This was an important trading post where Tibetans would exchange furs for guns and bricks of Chinese tea and today it still has the feel of a border town. The weather in Ya'an is relatively mild, but be prepared for an occasional snowstorm during the winter.
