Actually, the story is very simple. A hard-working temporary female teacher suffers from too much labor and different treatment from a regular teacher every day, and faces a gloomy life every day, because she has an idle boyfriend who directs idle eating and drinking and never does it herself.
Zhu Xiao, who has evil thoughts, feels that he has found a "card" that can knock down Huiying, and intends to take it away from Huiying who owns everything.
The contrast of the active reversal in the last paragraph of the film made the audience breathe a sigh of relief. The whole story revolves around the struggle of two women, and the description in my heart is very successful. In the increasingly fierce war between two women, the reversal of strength and the ambiguity of good and evil are the most ironic places in the film. It always reminds me of the sentence that I once disagreed with.
