When the duke of Zhou buried his family, he dreamed that the serpent had got into his master's grave?

I'm familiar with your dream. What I did was this: I dreamed that I had been trying to climb up in the grave, but I just couldn't climb out. I don't know how many times you did it. Later, after about 1 year, I went out, but my dream did not appear. What I say is pay attention to safety and don't show off.
