Panjin in the context of "Panshan County"

Liaodong Bay is largest and longest of the three main bays of the Bohai Sea, the innermost gulf of the Yellow Sea. The other two bays are Laizhou Bay to the south and Bohai Bay to the southwest.

Although named after the Liaodong Peninsula (which forms its eastern shore), the bay is located directly south of the Liaoxi region, almost entirely west of the Liao River. It is bounded by the coastline of cities from southern Liaoning province (Dalian, Yingkou, Panjin, Jinzhou and Huludao) and eastern Hebei province (Qinhuangdao and Tangshan), between the Laotieshan Cape at Dalian's Lüshunkou District in the east, and the Daqing River estuary (which is an old southern mouth of Luan River) at Tangshan's Laoting County in the west. The bay is a source of ecological importance and exhibits rich biodiversity.

The Daliao River (simplified Chinese: 大辽河; traditional Chinese: 大遼河; pinyin: Dàliáohé, "Great Liao River") is a major river system in eastern Liaoning province of Northeast China, and formerly the main distributary of the lower Liao River until 1958. The Daliao River proper is formed from the confluence of three rivers at the border between Anshan's Haicheng city and Panjin's Panshan County, after where it runs a length of 94 kilometres (58 mi) covering a catchment area of 1,926 square kilometres (744 sq mi), before coursing in meanders southwest and draining into the Liaodong Bay just west of Yingkou.

The principal river of southern Northeast China, the Liao River, historically bifurcates into two distributaries near the Liujianfang Hydrological Station (六间房水文站) at Xinkaihe Town (新开河镇) of Anshan's Tai'an County, forming the Liao River Delta. The eastern distributary, called the Wailiao River, was originally the larger one and the main body of lower Liao River. It travelled southwards to pick up two large tributaries the Hun River and Taizi River, at a confluence locally referred as the "Trident River" (三岔河). After the three rivers merged, the resultant large river then adopted the new name as Daliao River.

Yingkou (Chinese: 营口; pinyin: Yíngkǒu) is a coastal prefecture-level city of central southern Liaoning province, People's Republic of China, on the northeastern shore of Liaodong Bay. It is the third-smallest prefecture level city in Liaoning with a total area of 5,502 square kilometres (2,124 sq mi), and the ninth most populous with a population of 2,328,582 as of the 2020 census, of whom 1,228,198 lived in the built-up (or metro) area made of three urban districts (Zhanqian, Xishi and Laobian) and one county-level city (Dashiqiao). It borders the sub-provincial city of Dalian to the south, the prefectural cities of Anshan to the north and east and Panjin to the northwest, and also shares maritime boundaries with Jinzhou and Huludao across the Liaodong Bay to its west.

Located on the east bank of the Daliao River mouth, Yingkou is an important port city, with the Port of Yingkou being the second-largest container port in the Bohai Sea (after the Port of Tianjin) and Northeast China (after the Port of Dalian), the tenth-largest nationwide, and the 25th-busiest worldwide. Yingkou is classified as a Medium-Port Metropolis.

The Liaohe Plain is a paddy plain located in the southern tip of Northeast China, part of the greater Northeast China Plain. The Liaohe Plain is one of the most important industrial zones in Liaoning, and with a cultivated land area of 144 million hectares, the area of the paddy-growing fields of its rice field station has increased by 977.1 sq km, from 1988 to 2006.
