In the statistical process of metaphorical images, it is found that although some images meet the requirements literally, they are not actually the objects of investigation. For example, when the images of "flowers" are counted, there are "flying flowers", i.e. catkins, which are not the plants "flowers" to be investigated. For example, when the images of "willows" are counted, the "willows" in the name of "Liuyong" are also listed. In case of these situations, they will be deleted manually and will not be included in the statistical scope to ensure that the statistical results are consistent with the research content.<br>
