There is a pine tree in front of the grave one and a half meters, is that ok?

Pure superstition! As long as it doesn't get in the way, it's not good to get in the way What is wrong with believing? I am superstitious. I dissect dead people all day, and no ghosts haunt me. Don't believe those fortune tellers and geomantic omen, they all fool 250. They are so good at calculating, why can't they calculate how to be president? Ghosts and gods all come from their own hearts.
