《宋史·列传·卷一百四十六》
德寿宫正用砖修石池，在池内用水银使金凫鱼飘浮于上，孝宗经过此地，高宗指给他看说： 宫内水银正缺乏，这是从汪尚书家中买来的。 孝宗大怒说 ：汪应辰力说我置房廊与民争利，自己却贩卖水银。 汪应辰知道后，极力请求去职。
德寿宫方甃石池，以水银浮金凫鱼于上，上过之，高宗指示曰： 水银正乏，此买之汪尚书家。 上怒曰： 汪应辰力言朕置房廓与民争利，乃自贩水银邪？ 应辰知之，力求去。
Deshou Palace was repairing the stone pond with bricks and used mercury in the pond to make the golden orfe float on the surface. When Emperor Xiaozong passed by, Emperor Gaozong pointed to it and said: "The palace is just short of mercury, and these are bought from the Wang Minister's house." Emperor Xiaozong said angrily: "Wang Yingchen contradicted me on building verandas and courtyards and competing with the people for profit, but he himself traded in mercury." After Wang Yingchen found out, he made every possible effort to ask to leave office.
