The banks of the North River used to be suburbs, so "ancestors" used to live there. The land development in the north was earlier, and many factories in the 1980 s were there; The south bank of the North River started construction in recent years, and its popularity is not as good as that of the north bank. If the living environment on the north shore is good, at least you don't have to hear the noise of construction all day. Finally, the aspect of "the land is rich and prosperous" varies from person to person, and it is not unreasonable for people to say that "the land is blessed".
