It is helpful to reveal the personality characteristics of the characters and make readers know these four writers better. For example, about the meeting between Turgenev and Flaubert, the author said: "... they often hit it off, and when they meet, they are all inner joy rather than mutual understanding." The discussion here tells readers that Turgenev and Flaubert have the same ideas and philosophical views, the same interests, lives and dreams, the same literary concepts and fanatical ideals, and the same appreciation and erudition, so they have already surpassed the "joy of mutual understanding" but "inner joy of the soul", which makes readers have a deeper understanding of the relationship between the two great writers.
