What is the difference between "contrast" and "rendering" in Chinese expression? Thank you, everyone.

Comparison: 1. When writing, first describe from the side, and then lead to the theme, so that what you want to express clearly stands out. 2. generally refer to the foil, which is more prominent: blue sky ~ white clouds. Rendering: 1 A technique of expression in literary and artistic creation. Highlight the description, explanation and comparison of the writing object. 2. refers to the extravagance and exaggeration of things. Rendering belongs to frontal description and contrast belongs to profile description, which is their most essential difference. Second, it depends on whether the support and the subject belong to each other. Rendering and contrast express the center through specific descriptions. If the concrete description in the rendering foil is in front of the bracket, then the center to be expressed is the subject. In rendering and contrast, the relationship between the bracket and the subject is different.
