Imitation of handwriting refers to the words written by the actor in order to divert attention, escape the blow or frame others, and imitate others' handwriting. According to the way of imitation, it is generally divided into three types: copying handwriting, copying handwriting and imitating strokes by memory. Copying handwriting means copying while looking at the handwriting of the imitated person. Copying handwriting is a method of word-for-word tracing on the basis of other people's handwriting by means of light transmission, copying, suppression and reverse rotation.
