The so-called "conciseness" means expressing the richest connotation with the least words. The so-called "implication" means that in addition to the literal meaning of language, there are implications and overtones. The so-called "vivid and appealing" means using rhetoric more. For example, "Jasper adorns trees, and thousands of green silk tapestries hang down", "Jasper" is a metaphor for color, and "silk tapestries" is a metaphor for shape, which vividly shows the characteristics of green willows and slender willows.
