Expression techniques are divided into three categories: lyrical techniques, descriptive techniques, and rhetorical techniques.
1. There are two types of lyrical techniques: direct lyricism and indirect lyricism. Indirect expression can be divided into expressing feelings by borrowing scenery, conveying one's aspirations through objects, and embodying reasons through objects.
2. Descriptive techniques mainly include: foil (front and reverse), association and imagination (combination of virtual and real), contrast, line drawing, combination of dynamic and static, rendering, etc.
3. Rhetorical techniques, mainly including: metaphor, personification, exaggeration, pun, allusion, antithesis, synaesthesia, etc.
Other techniques: suppressing the desire to promote, symbolizing, endowment, comparison, excitement, etc.
