Jiangbei Province, Xiaolu City.
Xiaolu City is famous for two things, one being its colorful pottery, the other being the notorious "Shishan Prison".
Shishan Prison is a debtor's prison, specifically for incarcerating bankrupt individuals and the poor who owe taxes.
Unless friends or relatives are willing to lend a hand, there are only two outcomes for those unlucky enough to be locked up in Shishan Prison: to either die of illness in the gloomy, overcrowded cells or to perish from relentless hard labor day after day.
After the military government took over Xiaolu City, Shishan Prison was also requisitioned, and no longer just confined to locking up debtors.
