有没有人举下具体的例子,什么是十八线城市?有什么特点让人称其为“城市”而非别的什么。
Wiki 上的 City 定义是:
A city is a human settlement of notable size. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication.
