Wang Xifeng, on the complicated stage of Jiafu, used her wisdom and skills to weave a breathtaking repertoire. Although she is illiterate, this has not become a constraint for her to move forward, but rather a unique advantage. In the big family of Jiafu, she is like a fish in water between all kinds of intricate interpersonal relationships, with her sharp eyes and intelligent mind, insight into everything, and dissolve everything.
She may not be able to quote the scriptures like the rest of the family, but she has a surprising strategy and a convincing way of doing things. Whether it is the internal and external affairs of the family, or the joys and sorrows of the old and the young, they are all under her control. Jia's mother's love and trust in her was won by her own ingenuity and wit. When dealing with family affairs, she always solves problems in an unexpected way, showing a different kind of wisdom and skill.
Wang Xifeng, despite his illustrious family background and intelligence, is an illiterate exception. There are many details, both bright and dark, in the book that reveal this fact. The little boy next to her, Caiming, is her right-hand man in reading. At the critical juncture of the raid of the Grand View Garden, Cai Ming read Pan You'an's letter to Si Qi for everyone;Sister Qiao encountered ghosts in the Grand View Garden, and it was also Caiming who flipped through the "Jade Box" to seek protection. Even for such an elegant thing as the Poetry Society, Wang Xifeng contributed generously, but he was unable to join the Poetry Society because he was illiterate. She herself once admitted that "I have not been literate since I was a child", and she frankly faced this shortcoming. Compared with Tanchun, although she praised Tanchun for "literacy, another layer of power", she did not have a bit of self-deprecation. Whether it is a subjective self-report or an objective evidence, it is indisputably provable that Wang Xifeng is indeed an illiterate person.
But what is puzzling is that Wang Xifeng has been raised as a boy since he was a child, and even received an education. In "Dream of Red Mansions", when Lin Daiyu first entered Jia's mansion, Jia Min revealed this fact to her: "I once heard my mother say that Jia Lian, the son of my uncle Jia Yu, married the niece of my second uncle's mother, Wang, and she was raised as a boy since she was a child, and her scientific name is Wang Xifeng." "Why Wang Xifeng is being raised like this, presumably because there is no boy in the family, so he can only let his daughter play the role of a boy.
Wang Xifeng's scientific name is not his real name, but the name used when he entered the school. It is mentioned in the book that Wang Xifeng's scientific name is Sister Feng, which proves that she once stepped into the school hall when she was a student. However, what is puzzling is that Wang Xifeng, who once enrolled in school, is illiterate. This is in stark contrast to her illustrious family background and her strong, crisp personality. 
The military attache of the Wang family for generations, born in the martial arts school established in the third year of the Qingli of Renzong of the Northern Song Dynasty, is the pioneer of the college of higher learning. During the Hongwu period of the Ming Dynasty, martial arts set up subjects in Confucianism to teach military attachés. In the orthodox years of Yingzong, the Liangjing martial arts school was established, and the disciplines were divided into two categories: one is the "Primary School", "Analects", "Mencius", and "University", and the other is the Five Classics, the Seven Books, and the Biography of the Hundred Generals. Students are required to choose one of the various books to study and understand the main meaning of the book. It can be seen from this that if you want to further your studies in martial arts, you must have a certain cultural foundation.
However, Wang Xifeng does not seem to have received such an education. If she does enroll, then she should be able to read and write. Therefore, it is reasonable to speculate that Wang Xifeng's scientific name may be just a charming disguise, a means used by the author, Cao Xueqin, to deceive readers.
Dream of Red Mansions is full of contradictions and plots that are difficult to distinguish between truth and falsehood, and many places seem to be carefully set traps by the author. Therefore, we should not delve too deeply into Wang Xifeng's scientific name, so as not to fall into the ecstasy set by the author. 
Wang Xifeng's intelligence is not accidental, but stems from the family education she received since she was a child. Although she is illiterate, her parents or tutors may have educated her in a non-traditional way, focusing on practice and experience rather than being limited to book knowledge alone. This kind of family education has equipped her with the ability to deal with complex affairs and a keen sense of observation, which has made her comfortable in Jiafu.
The concept of education in Jiafu is also worthy of our attention. Jiafu is not like ordinary feudal families, which only pays attention to the cultural education of children, but pays more attention to pragmatism and the cultivation of practical ability. Under this concept of education, although the children of Jiafu do not necessarily have a deep cultural background, they have excellent management and interpersonal skills. This is also one of the important reasons why Wang Xifeng was able to gain a foothold in Jiafu.
Wang Xifeng's story tells us that a person's wisdom and skill do not depend entirely on written knowledge. Practical experience, keen observation and judgment are equally important when dealing with complex interpersonal relationships and affairs. We should focus on developing these skills in the family and in society, while avoiding over-reliance on book knowledge and neglecting the importance of practical experience.
