What Aunt Sa said is actually a microcosm of many people in reality. She is snobbish and greedy, which is understandable. Actually, think about it Are there few people around like Aunt Sa? The final transformation is a good wish of the screenwriter. Aunt Sa is a character in the play, and her final transformation has a certain humanization. After all, the audience's psychology still expects truth, goodness and beauty.
I think the most unforgivable thing is You Gong, who finally followed Aunt Hong and didn't repent at all.
