Shanxi Province, China

People in most regions of Shanxi speak dialects of Jin, a subdivision of spoken Chinese. However, dialects in the southwest, near the border with Henan and Shaanxi, are classified as part of the Zhongyuan Mandarin subdivision of the Mandarin group rather than Jin. In terms of characteristics, Jin dialects are generally distinguished by their retention of the entering tone from Middle Chinese. In this respect they are unique in all of northern China, as most of the surrounding Mandarin dialects (spoken over the remainder of northern China) have lost it. (In central and southern China, it is much more common for the entering tone to be kept.) Jin is also noted for extremely complex tone sandhi systems.
Shanxi cuisine is most well known for its extensive use of vinegar as a condiment and for its noodles. A dish originating from Taiyuan, the provincial capital, is the Taiyuan Tounao (太原头脑, literally "Taiyuan Head"). It is a soup brewed using mutton, shanyao (山药, Chinese wild yam), lotus roots, astragalus membranaceus (黄芪, membranous milk vetch), tuber onions, as well as cooking liquor for additional aroma. It can be enjoyed by dipping pieces of unleavened cake into the soup, and is reputed to have medicinal properties.
