Opening a book bar was a promising investment, but the price was an important issue to consider. The following are some of the charging models that can be considered: 1. Charging by chapter or book: Charging according to the number of chapters or books purchased by the reader. For example, if a reader bought all the chapters of a novel, they could charge according to the price of the book. The other model was to charge according to the price of the chapters. In other words, readers had to buy a certain number of chapters to read the entire novel. 2. Charging by time: You can charge according to the time the reader spends reading the novel. For example, if the novel was charged by the hour, then a timer could be set. After reading the novel, the reader would have to pay. 3. Charging based on reading volume: You can charge based on the number of readers reading the novel. For example, if you set a daily or weekly reading limit, you would have to pay if you exceeded it. 4. Charging according to service fees: You can provide some additional services such as consulting services, translation services, editing services, etc. These services could be used as an additional source of income and could increase reader satisfaction. The above are some of the possible charging models. You need to choose the most suitable charging model according to the genre of the novel, the reader group, and the market demand. At the same time, he had to consider factors such as cost, profit, and competitors to ensure that the book's pricing and charges were reasonable.
