Who is busy with the topic of the Three Kingdoms?

It depends on the type of your book. If it is based on the official history of the Three Kingdoms, we can write such serious and rigid topics as "Historical and Cultural Research of the Three Kingdoms" and "Essays of Three Kingdoms Characters". However, if it is a novel or a rambling genre, we can consider titles such as Dream of the Three Kingdoms, Mourning of the Three Kingdoms or Melancholy of Red Cliff, or more explosive titles such as The Entanglement and Entanglement of Three Men and The Textbook of Men's Machiavellian. Everything depends on what you think.
