Jiangsu is an eastern coastal province of the People's Republic of China. It is one of the leading provinces in finance, education, technology, and tourism, with its capital in Nanjing. Jiangsu is the third smallest, but the fifth most populous and the most densely populated of the 23 provinces of the People's Republic of China. Jiangsu has the highest GDP per capita and second-highest GDP of Chinese provinces, after Guangdong. Jiangsu borders Shandong in the north, Anhui to the west, and Zhejiang and Shanghai to the south. Jiangsu has a coastline of over 1,000 kilometers (620 mi) along the Yellow Sea, and the Yangtze River passes through the southern part of the province.
The Huai River, formerly romanized as the Hwai, is a major river in China. It is located about midway between the Yellow River and Yangtze, the two longest rivers and largest drainage basins in China, and like them runs from west to east. Historically draining directly into the Yellow Sea, floods have changed the course of the river such that it now primarily discharges into the Yangtze. The Huai is notoriously vulnerable to flooding.
Suqian is a prefecture-level city in northern Jiangsu Province, China. It borders Xuzhou to the northwest, Lianyungang to the northeast, Huai'an to the south, and the province of Anhui to the west.
Hongze Lake, previously known as Lake Hungtze or Hung-tse, is the fifth-largest freshwater lake in China. Although it is known to have existed from antiquity, it drastically increased in size during the Qing when the Yellow River—then still flowing south of Shandong—merged with the Huai. The increased sediment and flow combined to greatly expand the lake, swallowing the previous regional center of Sizhou and the Ming Zuling tombs. During the imperial and republican periods, the lake formed part of the border between Jiangsu and Anhui provinces but since 1955 the previous borders have been shifted to place it entirely under Jiangsu's administration. It is now encompassed by the counties of Sihong and Siyang in Suqian Prefecture and Xuyi and Hongze in Huai'an Prefecture. Since the establishment of the People's Republic of China, the lake has generally decreased in size as more of its inflow has been diverted for irrigation.
The Battle of Huaiyin–Huai'an, also called by the Campaign to Defend Huaiyin-Huai'an (两淮保卫战) by the Chinese Communist Party, was a month-long battle between the Nationalists and the Communists during the Chinese Civil War for the control of Huaiyin and Huai'an, the two richest cities in China. Nationalist forces won the battle.

The Ming Ancestors Mausoleum, Ming Ancestor Tomb, or Zuling Tomb was the first imperial mausoleum complex of the Ming dynasty, constructed at a geomantically advantageous site near the inlet of the Huai River into the west side of Hongze Lake in present-day Xuyi County, Huai'an Prefecture, Jiangsu Province, China. Built between 1386 and 1413 by Zhu Yuanzhang—the Hongwu Emperor who founded the Ming—and his son Zhu Di the Yongle Emperor to display their filial piety, it was located north of the town of Sizhou, where the ancestors of the dynasty had lived. The remains of the Hongwu Emperor's grandfather Zhu Chuyi are known to have been disintered and moved to the site. He, his father Zhu Sijiu, and his grandfather Zhu Bailiu were posthumously revered at the site as honorary emperors, Zhu Chuyi as the Xi Ancestor of the Ming (Xizu), Zhu Sijiu as the Yi Ancestor of the Ming (Yizu), and Zhu Bailiu as the De Ancestor of the Ming (Dezu).
