Which district does Xuzhou Chengjia International Garden City belong to? What's the postal code?

Chengzhi International Garden City Address: Jinshanqiao Economic and Technological Development Zone, with Xu Hai Road in the south and No.1 Road in the west. Address: Gulou District, Xuzhou City, Jiangsu Province, with the postal code of 22 1000. Note: Postal code 22 1000 is not necessarily the most detailed regional postal code of Jiangsu Gulou, but it can meet the needs of ordinary mailing letters and articles to Gulou. The more detailed address below the drum tower must be provided to the post office. For example, the detailed postal code of a street in Wuhan, Hubei Province is 43002 1, but the found postal code of Wuhan, Hubei Province is 430000. Letters and articles with postal code of 430000 can be effectively delivered to all places under the jurisdiction of Wuhan City, instead of having to be written as 43002 1 to be delivered correctly.
