在中国过去数十年的发展历程中，房地产与土地财政曾是无可置疑的拉动经济的主力军。来自财政部的数据显示，2021年，全国国有土地使用权出让收入约8.7万亿元，达到历史峰值。也是在这一年下半年，房地产市场进入了下行调整周期。
This heuristic can be illustrated by the following design. Let’s say we have an application that generates a report, compresses it with zip, and saves it to the disk. With this heuristic in mind, we wouldn’t want the report generation to depend on the zip algorithm. A change from zip to LZMA algorithm shouldn’t affect the report generation. Likewise, the compression module shouldn’t depend on the file storage module. If we follow that heuristic, we will be able to change file storage to network storage without affecting compression or the report module. (By the way, this design might not be ideal, for instance, these tasks are too small to be modules, but I hope it conveys the meaning of this heuristic).
