Is it better to write the beginning of the novel directly or to describe the environment?

Whether the beginning of the novel was written directly or the description of the environment was good depended on the genre and writing style of the novel. If the novel was a suspense, mystery, or horror type of novel, then writing about the actions or discoveries of the protagonist or murderer at the beginning of the novel could allow the reader to enter the story situation faster and increase the sense of suspense and tension. If the novel was about life, emotions, nature, etc., then the beginning of the novel could better show the background, atmosphere, and scene of the story so that the readers could better understand the environment and background of the story and better integrate into the story. The effect of writing directly at the beginning of the novel and describing the environment depends on the genre and writing style of the novel, as well as the reader's reading habits and preferences.
