209. 此地无银三百两。
[误] There isn't 300 liang of silver buried here.
[正] A guilty person gives himself away by conspicuously protesting his innocence.
注：民间故事，有个人把银子埋在土里，上面写了个字条：“此地无银三百两”；他的邻居阿二把银子偷走了，也写了个字条：“隔壁阿二不曾偷。 ”
Folk tale. A man buried his silver in the ground and put up a note, saying: "Three hundred ounces of silver is not buried here." His neighbour Ah Erh stole the silver and also put up a note with this: "Your neighbour Ah Erh didn't steal it." ---A metaphor for one's being exposed by one's own vindication. 与上句一样，对不清楚故事背景的人，只有把一切解释得明白一点了。
