Historical Comparison

Sanitation
Contrary to popular beliefs, the Romans were definitely not as clean as we like to think. Public toilets, for example, had the notorious reputation of exploding, terrifying customers from time to time.

Proto-Industrialization
The Ymaryn's Ironworks is comparable to Song Dynasty China's proto-industralization process. However, unlike the Song Dynasty, the extent of Ymaryn's proto-industrialization did not lead to wildspread deforestation. Instead, the industrial growth of the Ymaryn encouraged further forestry growth.

Governance
Like in pre-Tang states, Ymaryn bureaucrats are not selected by a civil service exam and instead are descended from noble families who train them in the skills needed to be a bureaucrat. However, the Ymaryn is capable of building the social infrastructure for a civil service exam.
