Huludao in the context of "Chaoyang, Liaoning"

Dalian (/dɑːˈljɛn/ dah-LYEN) is a major sub-provincial port city in Liaoning province, People's Republic of China, and is Liaoning's second largest city (after the provincial capital Shenyang) and the third-most populous city of Northeast China (after Shenyang and Harbin). Located on the southern tip of the Liaodong peninsula, it is the southernmost city in both Liaoning and the entire Northeast. Dalian borders the prefectural cities of Yingkou and Anshan to the north and Dandong to the northeast, and also shares maritime boundaries with Qinhuangdao and Huludao across the Liaodong Bay to the west and northwest, Yantai and Weihai on the Shandong peninsula across the Bohai Strait to the south, and North Korea across the Korea Bay to the east.

As of the 2020 census, its total population was 7,450,785 inhabitants of whom 5,106,719 lived in the built-up (or metro) area made of 6 out of 7 urban districts, Pulandian District not being conurbated yet.

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.

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.
