Co-writing referred to the co-creation of a novel by multiple authors, in which each author contributed their own writing style and ideas. This form of writing usually required more collaboration and communication to ensure the quality of the entire work. In the process of co-writing a novel, each author needed to be clear about their writing goals and division of labor, and integrate their creativity and style into the work. At the same time, they had to negotiate and abide by the creative agreement to ensure the harmony and unity of the entire work. If there was a lack of communication or coordination between multiple authors, it might lead to differences in style, plot, or characters that would affect the quality of the entire work. Therefore, writing a novel together required each author to have a high level of communication and collaboration skills to ensure the success of the entire work. Working together to write a novel could stimulate the creativity and imagination of the author and increase the quality and influence of the work. At the same time, it could also help authors better understand each other and establish a better creative relationship, so as to obtain more creative inspiration and harvest more works.
