Urban communities on the Grand Canal consist of cities surrounded with ramparts, and slender and long streets formed along the coasts of the canal. Those cities in North China, are formed artificially and comparatively regular rectangles, while in Yangtze Delta their forms are made irregular hindered by creeks.In North China canals surrounding the cities mean moats and their main use is the defence of the cities, but in Yangtze Delta those creeks are for water transportation, irrigation and for everyday life. In the cities of North China waterways are not often seen. But in Yangtze Delta the cities have many waterways which play an important part in transportation and in other daily activities of the people.The scale of the towns of those long streets along the coasts of the canal depends upon the parts those towns play in transportation. In North China the farther the towns are situated from the walled cities, the less thriving are they, and that is also the case with Yangtze Delta, where, however, at the foot of a bridge of the canal those towns regain their activities.A phenomenon common to the north and south of the Yangtze is Su Ho Ton (Blind Alleys), which seem not to have been made purposely for the befence of the cities but to have been born spontaneously.
