Synaesthesia figure of speech, also known as empathy, is a figure of speech that uses images to transfer feelings when describing objective things, so that people's different feelings such as hearing, sight, smell, taste and touch can communicate and interlace with each other, and the words that originally expressed A sense can be transferred to express B sense, making the images more vivid and novel. Synaesthesia is to communicate the feelings of different senses, cause the transfer of feelings through association, and carry out the exchange and transformation of "writing feelings with feelings" among various sensory organs in literary creation and appreciation. It's the impression that a feeling transcends its own limitations and realizes that it belongs to another feeling. In synaesthesia, color seems to have temperature, sound seems to have image, and cold and warm seems to have weight. Say "bright" and "loud", as if vision and hearing are interlinked, such as "lively" and "calm", and feeling and hearing are interlinked. In modern psychology or linguistics, these are all "synaesthesia". It often uses the language of images to convey feelings, and by virtue of the mutual connection and reflection of feelings, it stimulates readers to associate and appreciate the aftertaste, thus rendering and deepening the artistic conception of poetry.
Second, the classification and examples of synaesthesia
According to people's physiological senses, synaesthesia can be divided into hearing, sight, smell, taste, touch and consciousness:
1, write vision with sense of smell.
Lin Bu's "Xiaomei in the Mountain Garden": "The shadows are shallow, and the fragrance floats at dusk." There are shades of incense, but there are no shades. "Dark fragrance", the light and shade of vision can communicate the light and shade of smell. "Dark fragrance" is actually a faint fragrance, which is used to describe plum blossom fragrance.
