[3] Yangxian County was then renamed Yixing Commandery (义兴郡; 義興郡; Yìxìng Jùn), in honor of Zhou Qi.

[3] In 589 CE, under the Sui dynasty, Yixing was re-designated from a commandery back to a county, and was placed under the jurisdiction of Changzhou.

[3] In 976 CE, Yixing County (义兴县; 義興縣; Yìxìng Xiàn) was renamed to the similar sounding Yixing County (宜兴县; 宜興縣; Yíxìng Xiàn), because of the naming taboo of Emperor Taizong of Song, who went by the personal name of Zhao Guangyi.

[3] Beginning in March 1983, Yixing County was placed under the jurisdiction of the prefecture-level city of Wuxi, which it remains part of today.
