First of all, I have not studied for a long time, and I am not a teacher. I am a little bastard. The following remarks are for reference only.

I think the second half of your article is well written. My understanding of Lincoln's story is: don't follow the trend. Lu You's poem means to apply what you have learned. It's an associative relationship, not a reciprocal relationship. The poem that leads Lu You at the beginning seems a bit out of place. Besides, I feel a little pedantic.
