The name Li Yi City was quite unique and attractive. However, when writing a novel, there were still some factors to consider, such as whether the role of the name in the novel matched the theme and style of the novel. The male protagonist's name usually had to be in line with the plot and character in the novel to better reflect the character's personality and characteristics. If Li Yicheng was an important character in the novel, he could consider adding more information and meanings to the name to better express the character's image and personality. For example, he could add the meanings that Li Yicheng represented, such as " courage " and " wisdom ", to better display the characteristics of the character. At the same time, he could also consider other Chinese characters to increase the flexibility and variety of the name. For example, the words "Yi" and "City" had a certain historical and cultural significance. One could consider adding other meanings to increase the interest and legibility of the name. The name wasn't the only deciding factor. It also needed to be considered according to the plot of the novel and the creation of the characters. I hope you can create an excellent novel!
