It belonged to Jiangsu in 53 years and Shandong in 48-53 years. During the Wang Puppet Period, it was called Huaihai Province.

Xuzhou has a strategic position in history, and it was built earlier. However, due to years of war and the flooding of the Yellow River, there are few buildings left over from the ancient city.

After liberation, it was not taken seriously by Jiangsu, so the present situation is rather embarrassing.

For example, Xiaoxian County and Dangshan County, which originally belonged to Xuzhou, were changed from Jiangsu to Anhui (changed to Xuyi and Sihong in 53 years), which caused the geographical embarrassment of Xuzhou's current development.
