《淮南子·说山训》
利用高地修建高台，顺随洼地开掘池塘，各自依顺地势特点，不能违背因地制宜的原则而随心所欲。
因高而为台，就下而为池，各就其势，不敢更为。
Use the high ground to build a high platform, follow the contours of the land to dig a pond, each respecting the characteristics of the terrain, and cannot violate the principle of adapting measures to local conditions and act arbitrarily.
