Xu Guangqi's "Agricultural Administration Encyclopedia" records that "today's northern soil is cheap and expensive in northern Hebei (cotton), while in the south, northern Hebei is boating in the south and cloth is boating in the north." This is the fifth question in the 20 1 1 Hainan History College Entrance Examination. The correct answer is D. The author Xu Guangqi knows that the background is the Ming Dynasty. Although business is the premise of cotton textile development, it cannot be reflected in the title. The title says "cotton is cheap in the north, cloth is expensive, but the opposite is true in the south", which shows that the trade and economy in the south is relatively prosperous, especially the "south is the opposite" mentioned above. This shows that the southern economy was superior to the northern economy at that time. B and c don't meet the question. Moreover, the maritime ban of the Ming Dynasty only opened a trading port in Guangzhou. So choose D, believe me, you can look at the correct answers in the college entrance examination questions over the years.
