38. Zhang, “Changing with the Yel-
low R iver,” 22. Zhang explains that
population growth, prosperity, and silk
production all flourished in the old course
region after 1048. If this - rather than our
hypothesis of decline - is correct, it makes
the relatively low density of counties and
prefectures there even more intriguing.
