如坐针毡
rúzuòzhēnzhān
[be on hot coals;be on nettles;be on pins and needles;feel as though one was lying on a bed carpet;walk on thorns] 形容心神不宁,不得安生
精神上的痛苦使人如坐针毡
人面兽心
rénmiàn-shòuxīn
[have the face of a man but the heart of a beast] 本为古代鄙视匈奴的词
夷狄之人,被发左衽,人面兽心.——《史记·匈奴传》
后指人的面孔,野兽心肠
又观顷日降附之徒,皆人面兽心,贪而无亲,难以义感.——《晋书·孔严传
