It means that the eight-character pattern is clear, and the so-called pattern is turbid. It means that the likes of the eight characters have no constraints in life, and the dislikes have constraints, which means that the pattern is clear. On the contrary, there are other conflicts in the fate of the eight characters, indicating that the pattern is turbid.
