The so-called copyright fee tag on Dumpling's works referred to the tag that the author used to mark the amount of copyright fee in the comments after the author published a work. These tags usually included "royalties/free","royalties/zero yuan","royalties/XXX yuan", etc. When readers checked the works created by Dumpling, they could know the creation cost of the work through the label, including the author's royalties, editing costs, promotion costs, etc. This way, readers could choose whether to read the work according to their own needs and choose the corresponding payment mode. The royalties tag was a way for Glutinous Ball to interact with the author. It provided a platform for readers and authors to communicate, and it also promoted the quality and quantity of Glutinous Ball's works.
