梟其首（占堯反說文倒首也謂斷首倒懸竿頭肆其辜也字或作梟說文不孝鳥也冬至曰捕梟磔之從鳥頭在木上二形通用也）。

梟其首 (pronounced with the fanqie 占堯 [xiāo]. The Shuowen jiezi says: "It means hanging a severed head upside down." That is to say, severing the head and hanging it upside down atop a pole to expose the crime. The character is also written as 梟. The Shuowen jiezi says: "An unfilial bird. On the winter solstice, they are captured, owl-like, and quartered; it is composed of 'bird' with its head atop 'wood'." Both glyph forms are used interchangeably.)
