The Commonality of Sian is a mammoth, socially progressive nation, ruled by Premier Sun Han with an even hand, and renowned for its compulsory military service, hatred of cheese, and punitive income tax rates. The compassionate, cynical, devout population of 9.077 billion Sianians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large government juggles the competing demands of Welfare, Education, and Law & Order. It meets to discuss matters of state in the capital city of Zi-jen Cheng. The average income tax rate is 54.4%, and even higher for the wealthy.

The large but underdeveloped Sianian economy, worth 268 trillion yuan a year, is led by the Automobile Manufacturing industry, with significant contributions from Information Technology, Retail, and Soda Sales. State-owned companies are common. Average income is 29,570 yuan, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Korvinism has been named as Sian's national religion, restaurants are required to specify whether their toilet paper was made in Sian, the typical murderer weighs 150kg and has hairy arms, and college students make ends meet by selling their kidneys. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Sian's national animal is the tiger and its national religion is Korvinism.

Sian is ranked 187,615^th in the world and 17^th in China for Largest Black Market, with 599 billion Standard Monetary Units.
