Special Xuzhou Dialect
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.
