I want to know the answer to the following question:
North Zhejiang and south Jiangsu are famed for their opulence and what else?
All the background I'm provided with is that "Since ancient times, north Zhejiang and neighbouring south Jiangsu have been famed for their prosperity and opulence[citation needed], and simply inserting north Zhejiang place names (Hangzhou, Jiaxing, etc.)". Is that enough to answer the question?
