Some people in rural areas believe in Feng Shui, but I don’t know if it is really a thing.

Absolutely, something particularly efficacious happened.

My mother's uncle was originally very happy. He was an official himself and did not believe in evil. He had two sons, the eldest was married and had children. About eight years ago, his family asked Mr. Geography to sort out the feng shui of their ancestors. He put on airs and turned a blind eye to Mr. Geography. I heard that he even insulted Mr. Geography, but his brothers took it very seriously. One month after the incident, his youngest son died of a slight cold, then his eldest son also died for no reason, then his grandson died of a fever, his old wife took poison because of sadness, and then his wife was too sad. He hanged himself and now he is alone, living at his grandmother's house. I saw him during the Chinese New Year and he looked very haggard.
