Use it for a specific theme.

To share my own, I think excerpting is not just a simple writing down of favorite poems, but a feeling when reading, and reading the same poem at different time periods will have different feelings, so the feelings are different.
I usually draw a vertical line to the right in the middle, write the original poem paragraph on the left, and the right corresponds to the time source and sentiment, and the sentiment at different times will be written separately.
In this way, it is not just a form of extraction, the most important thing is to learn from it.
There are many formats, and the one that suits you is the best.
