The rules for paying for monthly copies of best-selling novels usually varied according to the service provided. Generally speaking, the service supplier would calculate the monthly fee according to the price of the book and then distribute the fee equally to each reading night. For example, if the price of a book is 10 yuan, the service supplier might charge 50% of the fee, which is 5 yuan, and use the remaining 5 yuan to pay for every night of reading. Different service suppliers may adopt different charging rules and may adjust them under certain circumstances. However, under normal circumstances, the charging rules for monthly reading were based on the price of the book and calculated according to the number of reads.
