there are ---- more people in Hebei than in Yancheng

选择manymany more后接一个名词一定是个复数可数名词。若不接名词,则more本身就被看作是一个复数名词,表示复数概念。如：Some students are against the plan,but many more support it。一些同学反对这项计划,但是有更多人支持它。We have many more left。我们还剩下很多。much more后接一个名词,这个名词一定是个不可数名词。若不接名词,则more本身就被看作是一个不可数名词。如：The farmers have produced much more rice。这些农夫收了更多的稻谷。She has much more to do。她还有很多事要去做。
