Secondly, when writing, we should pay attention to the characters and thinking of that era, and the thinking and concepts of ancient people should not be too modern. If the protagonist can't get up, he will be invincible. He is extremely erotic and boring to watch. He is moderately erotic.
Knowing the famous families of that era, historical novels can involve political infighting, palace infighting and military affairs.
Military materials must be vivid, and the author must have his own unique view of history and find another way. Of course, it can't be too unreliable.
The protagonist's personality should be distinct and not perfect, and the characters should have appropriate defects, and slowly write the growth and transformation process of the protagonist.
Finally, there is the problem of the hostess, not too much. Women's main personality is distinct, don't be stereotyped, don't be feminist, and be gentle and delicate but not procrastinating when dealing with emotional scenes.
Finally, there are villains in the novel. Don't be silly. There must be several villains who are determined by their intelligence, but his character is also flawed, such as being too superstitious about money, power, reputation and so on.
These are my personal suggestions. Take a look, it may not work. Finally, I wish you an early writing!
