This is not a movie review, it's a personal opinion
Pay attention to these two places
The first one is when the mother-in-law saw her daughter-in-law sleeping with Aba, and she was in a fire. Lying on a tree by himself, the camera also gave a close-up of the tree
Finally became a hag, two people ran across the tree, one left and one right
My personal understanding is that the tree may symbolize the male, and the two females, who approach this issue as opposites. Mother-in-law is conservative, daughter-in-law is open. And the conservative mother-in-law is only for her own interests. Because he wanted Aba to sleep with himself instead of his daughter-in-law.
In the end, under the pressure of survival, the too selfish mother-in-law was destroyed.
