# Yizheng

Yizheng (simplified Chinese: 仪征; traditional Chinese: 儀徵; pinyin: Yízhēng) is a county-level city under the administration of the prefecture-level city of Yangzhou, Jiangsu province, China, with a population of about 600,000 (2007). It borders the prefecture-level divisions of Chuzhou (Anhui) to the north, Nanjing to the west, and Zhenjiang to the south.

## History
### Etymology

In 1013, the statues of several preceding emperors of the Song were cast in Jian'an (建安) military prefecture. Thus, the region was changed into Zhenzhou (Zhen prefecture, 眞州). Later, with the emperor's favor, a Taoist temple named Yizhen (儀眞) was also built, at where the former furnace was situated. Both zhen and yizhen mean "lifelikeness" in Chinese. The prefecture was named after the temple in 1117. Yizhen county was renamed Yizheng in 1723, because the homophone "zhen(禛)" as a part of the Yongzheng Emperor's Chinese name was deemed to be ineffable.

## Geography

On the northern bank of Yangzhou, Yizheng is situated in the north of Jiangsu, and the Yangtze River lies in its southern territory. The city borders Luhe District of Nanjing on west, the urban area of Yangzhou on east and Tianchang of Anhui Province on north. The city owns a riverbank of 27 km (17 mi), facing Zhenjiang in opposite of the river.
Two major bodies of water, the Yangtze River and the Grand Canal, run through Yizheng from west to east and from north to south, respectively, dividing the city into four fractions.
