What do you mean this person is unpredictable?

Complexity is unpredictable. In ancient times, it refers to strategists, that is, guiguzi, because they used sophistry, that is, golden words and jade words, to lobby governors and monarchs of various countries. Good use is good, and evil use is evil.

Sophistication is generally to reverse black and white and confuse people with some specious concepts, thus achieving a goal.

Therefore, the unpredictability of sophistry means that his sophistry is superb, reaching the point where people can't tell right from wrong, right from wrong and true from false. The higher level is the kind of sophistry that others don't know yet

Well-known examples are the militarists in the Warring States period, the legendary eight generals, the fake fortune tellers who set up stalls on the streets, the fake geomancers and so on. Another example is the deviation table.
