Chan Juan was a fan of online literature. She answered questions based on her knowledge of online literature. Chan Juan believed that many people didn't like to answer questions in books because of the following reasons: 1. A lack of trust: People may not trust the knowledge and answers in books because they may have been manually filtered and edited, or they may come from the perspective of an expert or institution. Although the answers in books can give people confidence, they may not necessarily be consistent with the actual situation. 2. Need to understand knowledge points: answering the questions in the book requires a certain amount of knowledge points and skills, which may be difficult for some people. They might need to spend more time learning and understanding the knowledge points to answer the questions in the book. Time constraints: For some people, they may not have enough time to answer the questions in the book. They may be busy with other tasks or work or need to solve problems as soon as possible to save time. 4. No interaction: The answers in some books may lack interaction. They may simply give answers without any other communication or feedback. This might make people feel bored and reduce their interest in answering questions. Although the above reasons may make people dislike answering questions in books, people still like to answer these questions. By interacting with people and exchanging books, people's needs could be better met and their knowledge level could be improved.
