As a fan of online literature, I think the two sci-fi novels that young people should read the most are Alive and The Three-Body Problem. Alive was one of Yu Hua's masterpieces. It narrated the life experiences of a Chinese farmer and reflected some major changes and problems in Chinese social history through his experiences. The novel showed the essence and meaning of human existence to the readers with simple and unadorned language and profound thoughts. This book is suitable for young people to read. It can let them understand the preciousness of life and the importance of cherishing every minute and every second. " The Three-Body Problem " was one of Liu Cixin's representative works. It was a science fiction novel. The novel discussed the development and future of human civilization by describing the conflicts and exchanges between alien civilizations and Earth civilizations. The deep and enlightening thoughts in the novel had a great impact on the young people's thoughts. This book was also suitable for young people to understand the charm of science fiction and the value of reading. These two novels have high literary value and depth of thought, allowing readers to understand different cultures and life experiences, which have great enlightenment for the growth and development of young people. Therefore, I think they are one of the novels that young people should read the most.
