First of all, the name should be mysterious, and you cannot tell people at a glance that they can guess what you are writing about by looking at the name; secondly, it should roughly reveal how brilliant the protagonist is and how twists and turns the journey is, which makes people I want to know what the protagonist has done and experienced; finally, the name must be catchy, so that people cannot remember what it is after reading it several times. These are my suggestions. If there are any shortcomings, please forgive me!
