Tienkin

Tienkin (: 天京, Tiēnkīn), is the of the Empire of Yinguo and the country's most populous city. Located in the southeast of Yinguo, the city has a special administrative status as the Imperial Capital, with a provincial level government of its own, divided into 20 districts. With a population of around 19 million people, Tienkin is one of the largest cities in the world and a, while also being the political, cultural, religious, and economic center of the nation, hosting the residence of the Emperor, the headquarters of the Government and the meeting place of the Imperial Court.

The history of the city starts during the Zhen dynasty, when it was founded as the city of Jiangjing. It remained one of the most important cities in southeastern Tarsis until it was sacked during the Second Hundred States Era, only starting to slowly recover during the rule of the Zhu dynasty. After the collapse of the Zhu during the Great Tragedy, the city became the rallying point of the former imperial family, and it was renamed to Tienkin by the first emperor of the Yin dynasty, becoming the capital of Yinguo. It survived the First World War relatively unscathed, but it was damaged during the Zhenian conquest of the Second Great War, and it subsequently became the center of Yinguonese resistance, returning to Yinguo's control during the Great Liberation Expedition. Reconstruction and development after the war modernized the city, and pushed it into the position of one of the most important cities in Tarsis, fueled by a rivalry with the Zhenian capital city of Daedo.

Today, Tienkin is considered by many to be the living heart of Yinguo, and the symbol of the reign of many Emperors. It is a touristic destination renowned for its many palaces, temples, and mausoleums, and while widely considered to be a city of traditionalism, the financial district of Xinshi hosts the headquarters of the most important Yinguonese companies, while the district of Xuanqiu is famous for its nightlife and liberal etiquette, and the country's best scientific and educational minds meet in the district of Zhongcheng.

Etymology
The name of Tienkin (天京, Tiēnkīn), carried by the city today, can literally be translated as "Heavenly Capital", having been named as such by the first emperor of the Yin Dynasty after the Reclaiming of the Mandate of Heaven. The name was intended to represent the blessings that the Heaven would bestow upon the new capital of the legitimate emperor, in contrast with the capitals of other pretenders that existed at the time. Tienkin is also known as the "Imperial Capital" (御京, Yùjīng), especially in administrative contexts, and this name is sometimes used while referring to either the administration of the city, or to the district of the city that hosts the Imperial Palace. During most of its history, from its founding by the Zhen dynasty, the city was known as Jiangjing (降京, Jiàngjīng), the "Lower Capital", and the name is still sometimes used during historical or touristic contexts.
