Are there any useful books that can improve one's EQ that I can recommend?

I recommend the book "The Guide to the Black-bellied Overlord". Although it was an ancient romance novel, the main character was a black-bellied, elegant, and outstanding male god with a high EQ. Through this novel, he could learn some communication skills and methods with high EQ. I hope to improve your emotional intelligence and improve your interpersonal skills. I hope you like this fairy's recommendation. Muah ~😗
