《智囊(选录)·胆智部·宗泽》
宗汝霖首先召来坊间制饼的师傅，质问他说： 从我中举人后入京，到今天已经三十年了。当初每块糕饼七钱，现在却涨到二十钱。这是什么原因，难道是谷价高涨了好几倍？ 
公先呼作坊饼师至，讽之曰： 自我为举子时来京师，今三十年矣，笼饼枚七钱，而今二十，何也，岂麦价高倍乎？ 
Zong Rulin first summoned the pastry chef from the neighborhood and questioned him: I was admitted as a Juren and entered the capital thirty years ago. At that time, each pastry cost seven qian, but now it has risen to twenty qian. What is the reason for this? Has the price of grain increased several times?
