This is Xuzhou's Hot Soup. You won't find this anywhere else in the country. The soup is usually eaten for breakfast, and you will definitely sweat after your meal, because the soup is so hot. The spiciness comes from lots of ground pepper and ginger. The soup also contains small pieces of chicken or eel, and that's about it - you can also have some eggs (egg drop) in it. Very delicious - don't miss it.
See my China travel page's "Food Folder 2003" travelogue for more mouth-watering dishes.
Most Xuzhou locals like to eat breakfast from street vendors because they make some of the most delicious local food. Your typical Xuzhou breakfast consists of a bowl of hot soup (Xuzhou style), fried bread sticks or pan fried dumplings. If you're buying the food to go, at most places you may have to bring your own containers to hold the soup and dumplings. But this is a great experience!
There is a special dialect of Chinese used in Xuzhou. The deviation from Mandarin Chinese is that the four tones (if you know what I'm talking about) are now changed. In general, anything that uses the first tone in regular Mandarin is now replaced by the third tone, the second tone is replaced by the first tone, the third tone is replaced by the second tone, and the fourth tone remains the fourth tone. Using this rule you can now speak the Xuzhou dialect of Chinese.
