3. The author's cleverness lies in that he did not show this love tragedy superficially and simply, but dug out the social root of this love tragedy from the depth of the characters' thoughts and personalities and from the relationship between people, thus fully exposing the cruel hypocrisy of feudalism and the decadent crime of the feudal ruling class. The theme of the work is not limited to the personal love tragedy itself, but around the central event, a lot of complicated contradictions and struggles have been carried out, depicting an extremely broad picture of social life, which shows that the whole feudal society has been riddled with holes, and is rickety.
