齧齒（上五結反考聲齧噬也字書云淺齩也從齒契省聲經文從口作嚙非本字）。

Gnashing teeth (齧齒) (the first character is wu + jie fan [niè]; Kaosheng: "齧 means to bite and chew." Character dictionaries say: "To bite shallowly." Formed with the chi [teeth] signific and abbreviated qi phonetic. The scripture text writes 嚙 with the kou [mouth] radical, which is not the original character).
