Seongnam

Seongnam (Zhenian: 성남), formally known as the City of Seongnam (Zhenian: 성남시), is the second most populous city in Zhenia's Gyeongin Province. Situated directly to the southwest of Daedo Special City while facing the Gulf of Danguk and sharing the Danbon Estuary with Daedo, it is a key component of the Greater Capital Megalopolis around Daedo, the largest metropolitan area in the nation with a combined population of almost 40 million. The city itself is one of Daedo's largest satellite cities today, being home to over 3 million residents and spanning over an area of over 1,000 square kilometers. The city was developed as a major of Daedo during the Daehwa dynasty, then declined amid the major relocation of the city's outport to what is now Shin Daedo, and grew once again as a major  of Daedo following Zhenian industrialization. In particular, the city has seen significant growth following Zhenia's economic resurgence after the Second Great War and the Third Republic, when it became the home of several projects aimed to alleviate overcrowding within Daedo.

A secondary outport and satellite city of Daedo, Seongnam has seen significant growth as a primarily residential city, with a considerable portion of its population commuting to Daedo. In recent years, the Zhenian Government has also provide stimulus packages to large public and private corporations to relocate some of their operations from Daedo and to planned new towns in the city, further propelling the city's growth. Thus, it is home to the regional operations centers of a number of prominent Zhenian corporations, including the primary semiconductor plant and on-site operations center of Jinmu Electronics. Due to its proximity to Daedo and its infrastructure, it has become one of the fastest-growing cities in the nation, with projections that its population would increase to 4 million by 1625 if the current trend continues.
