What is Confucius' attitude towards ghosts and gods?

Confucius' theoretical system focuses on human nature and pays little attention to heaven. His student Zi Gong said: "The articles of the master can be heard, but the words of the master can't be heard." Confucius did not explicitly deny the traditional view of destiny. When he was frustrated or depressed, he once expressed such feelings: "When the Tao does whatever it wants, it will be fatal; Tao will be abolished and destroyed. " But he didn't regard heaven as a will personality god. He said, "What does heaven say? When you are at four o'clock, everything is born. What is the sky? " He described the sky as a natural process of the four seasons, and the multiplication of all things was not mysterious at all. For ghosts and gods, Confucius kept a respectful distance from them and left them behind. When the student asked him about ghosts and gods, he replied vaguely, "How can you convince ghosts if you can't convince people?" In his view, the real world on this side is much more important than the unreal world on the other side. Although Confucius did not explicitly put forward atheism, he also showed quite distinct rational spirit. This opened a gap in the concept of destiny ghosts and gods, and had a positive impact on the development of atheism in later generations.
