She desires and envy the lives of others. She was once very vain. When she felt inferior because of poverty, she did not forget to take other measures to make up for her shortcomings. She would use a lot of French vocabulary to talk about fashion, In order to make up for the gap when they were poor, her sisters dressed her up as a seemingly rich woman, but later, she realized that love is more important than money, and finally gave up her vanity and married the poor but kind-hearted Mr. Brooke.

Jo is the second daughter of the March family, with a completely different personality, and is the core character in the novel. She is more boyish and incompatible with the traditional image of a lady. She hates things that should belong to girls, such as wanting to fight with boys without makeup or wearing a skirt. As a girl, I hate those silly girls who are full of girly resentments. She speaks bluntly and lacks scheming. She would read her favorite books and practice writing. Although she is stubborn and has a bad temper, she is very responsible. In addition, Joe has a strong sense of responsibility. When Beth contracted scarlet fever, she cared for her day and night.

Beth is the third daughter of the March family. She is simple, kind, dignified, and likes to play the piano. She is weak, timid and shy, which prevents her from completing her studies normally and can only stay safely at home with her family and help with housework. For her musical dream, Beth dared to break through herself. She was shy and said she wanted to learn the piano, but she would go if Mr. Lawrence made sure no one could hear her playing. It can be seen that Beth's innocence and shyness are vividly reflected here. Beth was also helpful, but she contracted scarlet fever while caring for Mrs. Hamel's children and was gone forever.
