What's the difference between new realistic novels and traditional realistic novels?

The most fundamental difference between the narrative style of new realistic novels and traditional realistic novels lies in the great change of the narrator's or implied author's perspective. Because traditional realistic novels take care of everything with reason, most traditional narrators take a higher view than the characters in life and stories. Writers of new realistic novels give up the care of reason or concept when dealing with life and characters, and their novels no longer show the condescending posture of the narrator. The authors of new realistic novels no longer rely on the power of reason or ideas to stand on the heights overlooking life and characters, but give up the arms of thoughts, relieve the author's privileges, walk into the masses, observe life from a downward perspective and observe every move of the characters in their works.
