What does the fortune teller mean by hurting yang and deceiving yin?

In other words, your life is not easy, and there will be many bumps; Yin deceit means that part of your potential energy is dominated by something that science can't explain. The so-called ghost. In fact, things are always accidental, but they also have their own shortcomings, which leads you to believe this statement. Just like when you do business and accidentally fail at a certain point, that kind of accident will subconsciously be considered cheating, but in fact, the problem is still found in your own fundamental problem.
