Jiangzhou subsequently remained under Qin Shi Huang's rule during the Qin dynasty, the successor of the Qin State, as well as the rule of Han dynasty emperors. Jiangzhou was subsequently renamed during the Northern and Southern dynasties to Chu Prefecture (楚州), then again in 581 AD (Sui dynasty) to Yu Prefecture (渝州), and later in 1102 during Northern Song to Gong Prefecture (恭州).[23] The name Yu however survives to this day as an abbreviation for Chongqing, as well as for the city's historic center, where the old town once stood; its name is Yuzhong (渝中, Central Yu).[2] It received its current name in 1189, after Prince Zhao Dun of the Southern Song dynasty described his crowning as king and then Emperor Guangzong as a "double celebration" (simplified Chinese: 双重喜庆; traditional Chinese: 雙重喜慶; pinyin: shuāngchóng xǐqìng, or chongqing in short).
