There were advantages and disadvantages to reading novels. Some novels could make people addicted to them, affect their real lives, and even cause physical and mental health problems. The novel might provide some illusory fantasy worlds, but it could also make people become unrealistic and lose their sense of reality. Reading novels required a lot of time and energy, and it could also affect one's sleep quality and work efficiency. Therefore, reading a novel required a moderate amount of concentration, not indulging in it, but also paying attention to protecting one's health.
