把这一句，留给此刻的你
In setting out the walls of a city the choice of a healthy situation is of the first importance: it should be on high ground, neither subject to fogs nor rains; its aspects should be neither violently hot nor intensely cold, but temperate in both respects.
在规划城市的城墙时，选择一个健康的环境是最重要的:它应该建在高处，不受雾霾和雨水的影响;它的相位既不应该非常热也不应该非常冷，但是在这两个方面都应该是温和的。
