The second Zhuge is the old farmer; Sanxiangu is a 45-year-old rural woman. Similarities: Both of them have feudal ideas. On the issue of children's marriage, both of them oppose Xiao erhei and Xiao Qin's free love, and they should arrange their marriage according to their parents' orders. Difference: ① Zhuge Liang is really superstitious. The third fairy is a false superstition. The second Zhuge is feudal and ignorant, but kind, cowardly and timid. The third fairy is a perverted selfish desire with a heavy selfish heart. She was originally a victim of feudal arranged marriage. The novel satirizes them both. But there is still a difference. The satirical attitude towards Zhuge Liang is mild. He is mainly superstitious and kind-hearted The satire on the three fairies is much sharper. But she still has a sense of shame, which means there is still room for irony. The two "immortals" finally changed. It shows that feudal superstition has gradually lost its market among the people in the liberated areas and the social atmosphere is changing.
