《太平广记·卷四百七十八·昆虫六》
夏季，毒蛇被这种虱子咬得难受，就把身体倒挂在江中浅滩水流很急的地方，让水冲去身上的虱子；或者卧在沙子里，把虱子碾压到沙中。
夏月，蛇为虱所苦，倒挂身于江滩急流处，水刷其虱。或卧沙中，碾虱入沙。
In summer, the poisonous snake was bitten by this louse and felt uncomfortable, so he hung his body upside down in a shallow river where the water was swift, letting the water wash away the lice on his body; Or lie in the sand and crush the lice into the sand.
