Zhang Zhilu is one of the most influential writers of children's novels in China since 1980s and 1990s. Zhang Zhilu's novel Illegal Wisdom was published by Beijing Children's Publishing House in February 2000. It has distinct artistic charm, rich aesthetic connotation and profound ideological significance, which is not only a new breakthrough in Zhang Zhilu's children's novels, but also an important achievement in China's children's literature creation at the turn of the century.

Illegal Wisdom is first of all a "plot novel" that is good at telling stories. The work revolves around the process of Meng Wei, a girl from Mengjiu Middle School, "detecting" Meishan (formerly known as Lu Yu), a boy in the same class, being implanted into the brain chip of Ladybug VII, and deducing the ups and downs and exciting scenes. There are three clues in the book: the first clue (the main clue, the dominant clue) is that I was surprised to find that Lu Yu, a senior two boy she worshipped before, was not only renamed Meishan, but also had a completely different personality, IQ and personality. In order to solve the mystery in her heart and save more Lu Yu, she went through fire and water with Zhou Guo. Finally, the secret of the mutation behavior of Lu Yu's implanted brain chip (microcomputer) was uncovered. The second clue (hidden clue) is that medical college brain surgeon Lv Xiangfeng invented the brain chip-in order to change his son's IQ, he implanted the chip into Lu Yu's abdominal cavity-Lu Yu lost his memory and denied his father-Lv Xiangfeng pretended to be Yu Tian Ming and sneaked into Mengjiu Middle School-and Lu Yu was finally rescued to restore his memory. The third thread (hidden clue) is a "ladybug with seven stars" plot, which attempts to control young students with high IQ through brain chips, and then control the evil purpose of human elites and the world. The book is set in the campus of Mengjiu Middle School and the whole world. Finally, the characters and contradictions in the book focus on deciphering the website "Ladybug Seven Stars" to rescue Lu Yu, which ends with a stranger plotting bankruptcy and Lu Yu being rescued. The whole story is full of twists and turns, full of suspense, bizarre twists and turns, touching the soul, and has a strong artistic effect that people have to read in one breath.

Secondly, Illegal Wisdom is a "growth novel" which combines fantasy with reality, science with human nature. Taking brain science research as the breakthrough point, the novel closely combines the development experiment of high-tech brain chip with the campus life and real social life of boys and girls, and shows a rich and complicated picture of contemporary youth life in a panoramic way. Bold and rich scientific fantasy extends the aesthetic tentacles of the novel to a broad artistic space. It provides readers with a variety of possibilities of interpretation and thinking, and this kind of imagination is not simply reflected in the weaving of stories, but an expression of truth, goodness and beauty and the growth of contemporary teenagers' lives, which permeates high-tech thinking into the daily details of real society, allowing us to realize the expectation of goodness, the growth of beauty and the strength of humanistic spirit while seeing that knowledge changes fate and science is power.

Thirdly, it is also an ethical novel with profound ideological connotation and practical significance of actively promoting quality education.

The so-called wisdom in "Illegal Wisdom" is "illegal" because the human brain chip that should benefit mankind is controlled and used by the bad guys. The "Seven Ladybugs" project implemented by strangers and Di Jiang in the novel is an evil plot to control the fate of the world by implanting chips into the brains of high IQ teenagers. Lu Xiangfeng, a kind-hearted scientist, will also lose his way because of the expansion of selfish desires and make a big mistake. However, young people in the process of growing up will become inhuman, selfish and rude "cold-blooded animals" if they only have wisdom, ability and knowledge without correct ethics. Illegal Wisdom reveals an extremely profound theme to us with vivid artistic expression: comprehensively promoting quality education is a profound educational revolution, an important condition for China to realize its dream of becoming a powerful country in 2 1 century, and quality education is the basis for paying attention to young people.

Illegal Wisdom reflects the writer's deep thinking on the quality education and spiritual life growth of the future generation of the nation, and shows the sense of hardship and wisdom of being brave in facing problems and being good at analyzing problems. It is a pioneer in China's children's literature creation at the turn of the century, and also a major breakthrough in children's literature which contains human emotions and pays attention to artistry. In a word, it is a very rare masterpiece of children's novels, and its publication will surely win the welcome of young readers.
