This is before the Jurchen invasions.

A rime book issued by the Song gov't.

Baike just glosses the prefectural room as the dwelling place of an official. I don't think he's governor yet-- Baike says he's a 知州 (senior provincial gov't official), though I guess that might be a translation choice because Wiki uses 'magistrate' for what this book is calling 'governor'.

Baike really wants to make this sound like Zhao Mingcheng is all about simplicity, which seems... wrong...
