Its administrative area corresponds roughly to modern Zhejiang, Shanghai, and southern Jiangsu (the portion east of Changzhou, between Lake Tai and the Yangtze).

The fertile Yangtze River Delta lay within Liangzhe Circuit, as did Lake Tai.

Liangzhe Circuit was created in 997, about 19 years after the Wuyue (907–978) king Qian Chu surrendered his kingdom to the Song dynasty.

(In 1127, following the Jingkang incident, Zhao Gou (Emperor Gaozong) reestablished the Song dynasty in Hang Prefecture, which he renamed to Lin'an Prefecture in 1129.)
