I would like to ask your understanding of the following two words and give your own views. It would be better if you could give an example.

Coarse and fine: Generally speaking, things are coarse and fine, but sometimes they are meticulous. . . For example, Zhang Fei embroidered, but people who are usually careless can also have a nuanced side.

Rough details: focus on some things, but ignore some key points, which eventually leads to bad results. . . For example, I am very focused on stocks, and some judgments are not well grasped, which will eventually lead to bad consequences.
