To tell the truth, I have never felt the significance of reading ancient poems. More precisely, I don't read ancient poems for some special reason. I like to see some green plants. Does it make sense? I like taking a leisurely walk. What's the point? I think I read ancient poems only because of their beauty. In my eyes, a poem about flowers may be more beautiful than real flowers, because the flowers you see in your heart are always more desirable than the flowers with defects in reality.
As for reading, different people have different views. Different people will have different views on the same thing, and the same person will have different gains in different moods. I always like to look at what I have read again after a long time, and I will always find differences, see my own changes and unchangeable things from these differences, and then feel happy.
