I want to know the answer to the following question:
What is the name of the area of land around Nanjing?
All the background I'm provided with is that "The area around Nanjing is called Hsiajiang (下江, Downstream River) region, with Jianghuai (江淮) stressing northern part and Jiangzhe (江浙) stressing southern part.". Is that enough to answer the question?
