《管子·四时》
国家既然有四时的不同政令，坚决执行着圣王的政事，那么，春夏秋冬四时应做的事情就要安排得各得其所，还要同时以上述 三政 作为必要的辅助。
国有四时，固执王事，四守有所，三政执辅。
Given that the country has various political orders for the four seasons and strictly carries out the policies of the sage king, the things that should be done in the four seasons of spring, summer, autumn, and winter should be arranged in a harmonious way and assisted by the aforementioned three policies at the same time.
