In the technique of characterization, The Story of Bean Juice inherits the tradition of Dream of Red Mansions. Lu Xun talked about the characterization of Dream of Red Mansions, saying that not all the good people are good, and not all the bad people are bad, so they are living characters. The same is true for The Story of Bean Juice. In the novel, except for the caricature of Liu Laifu, a dragon-like character, the rest of the people, though good or bad in character and high or low in temperament, all bring their own strengths and weaknesses, strengths and weaknesses, and are presented together in front of the reader. The Fourth Master, Mo Jiang and Liu Cheng Gui all carry the old culture's legacy, but in the writer's writing and the old is different, difficult to categorize simply. The fourth master does not die to keep the old set, he appreciated Mo Jiang is different from the master of the appreciation of lackeys, the master appreciates the standard of lackeys is to their own loyalty and ability to do things, the fourth master appreciated is Mo Jiang's character temperament, which is based on a sense of equality. Mo Jiang has slavery, but she to Liu Chenggui to repay the grudge, to the fourth master is to the spring to repay the drip of grace, she is little demand for others, and their own efforts to pay, and because of their own pay to make others happy and feel pleased, this is the traditional culture of the value of the ingredients. Liu Chenggui can be said to be abominable, but when he was poor, sick and desperate to join Mo Jiang, he admitted that he was wrong and sorry for Mo Jiang. I'm afraid that there are a few sincere, so he can live peacefully with Mo Jiang for a few years, and difficult times did not take the bean juice alone, but also every day to the fourth master's family, so it can be seen that he can also think of others.

The novel takes a microscopic view and avoids grand narratives. Accordingly, the novel doesn't spread out a big plot, rarely relies on suspense to attract people, and doesn't create dramatic conflicts, but writes about the calm and trivial daily life. It is not easy to write well about daily life, and the success of The Story of Bean Juice depends on several aspects, one of which is the proper tailoring of the material. Mo Jiang's life was not characterized by great ups and downs, but there were definitely great downs. The worst part of her life was the twenty years from the time she left the palace to become Liu Chenggui's wife to the time she was taken in by the Fourth Master. The writer did not write positively, she did not want to render Mo Jiang's suffering to earn the reader's tears of sympathy, but concentrated on writing Mo Jiang was Ye family took in twenty years of life, her past through Mo Jiang's three narratives to fill out. This is in line with the tone of the first-person narrative, but also able to introduce the story of Mo Jiang and Liu Chenggui, and, more importantly, also shows the quiet, non-complaint, and resilient side of Mo Jiang's character: Mo Jiang's first narration is because the Fourth Mistress wanted to ask her about the scar on her face and was too embarrassed to speak up, and Mo Jiang took the initiative to talk about it, and said it in a light-hearted way; the second time is when "I The second time, when "I" asked Mo Jiang where she learned her cooking skills, she mentioned Liu Chenggui, which aroused "I"'s interest, and "I" mentioned this "bastard man" several times. She mentioned Liu Chenggui, which aroused "my" interest, and "I" mentioned this "bastard man" several times. Mo Jiang only told some intermittent stories about how she was chopped up and how she lost her gambling money, without any sadness or tears, and appeared to be very calm; the third time was the time to say goodbye, and it was still calm and quiet. The third time is to say goodbye, still calm and quiet. When the great disaster comes, do not take it easy, is the perseverance; through the trials and tribulations of the hard times and can be calm to face, is the resilience.
