As a fan of online literature, I understand that the definition of a good book may vary from person to person. However, it was generally believed that a good book was a book that could resonate with the reader, produce emotional resonance, or bring inspiration and thought. From this point of view, a good book didn't need a particularly stunning plot and character creation, nor did it need too much language skills or literary value. On the contrary, a good book needed to have enough depth and content to arouse the readers 'thoughts and reflections so that they could resonate with it. In addition, good books also had to follow certain readers 'needs and reading habits. For example, some readers might prefer suspense, science fiction, or history books while others prefer romance, fantasy, or light novels. Therefore, good books should be selected according to the interests and needs of readers in order to better meet their needs. To sum up, a good book needs to satisfy a certain depth and content to arouse the reader's thinking and reflection. At the same time, it also needs to meet the reader's interest and needs. Although a good book didn't necessarily need a particularly stunning plot or character, they needed to have enough depth and content to attract readers.
