Jinhae

Jinhae (Seomun: 辰海, Jinmun: 진해), formally the Jinhae Metropolitan Municipality (Seomun: 辰海廣域市, Jinmun: 진해광역시), is the second most populous city of Zhenia. As one of the five Metropolitan Municipalities of the nation, it is governed by the Jinhae Metropolitan Government. It faces the Gulf of Zhen, an inland sea of the Gulf of Danguk, to the east and borders the provinces of Balhae, Changbaek and Imhae respectively. Being home to over 15 million residents and its metropolitan area altogether forming the Taimir Delta Megalopolis, Jinhae is a major hub for trade, transportation and finance, as well as the largest city in mainland Zhenia today.

Originally a small fishing and trading outpost located just north of the of the Taimir River, what is now modern-day Jinhae grew into one of the most important cities in mainland Zhenia as it was selected as one of the first ten ports open to the Shindan dynasty in 1847 after the Treaty of Sanggyeong was ratified. Becoming a directly-governed city under Shindanese rule in the early days of the Zhenian Civil War, it became one of the centers of trade as well as the influx of goods, Zhenian migrants and Shindanese investment into the mainland; by the end of the 19th century, it had already overtaken Junggyeong as the largest Zhenian city outside the Danguk Peninsula. Although the city was burned to the ground due to allied air strikes during the later stages of the Second Great War, it was rebuilt during the Third Zhenian Republic as a hub of trade and finance in mainland Zhenia, with major segments being redeveloped over the years.

Although its stance as the "second heart of Zhenia" is being challenged by the growth of Changan and Shinhang, Jinhae remains the largest city in mainland Zhenia both by population and by economic size. The Port of Jinhae, with recent expansions, remains the largest in the nation, handling over 35 million TEUs in 2019, while remaining a major  in modern commerce. It is also home to the annual Zhenia International Trade Exposition, the single largest in the nation.
