Maoshan fortune-telling hall

Is Maoshan's fortune telling really accurate?

To tell the truth, fortune telling, like Chinese medicine, is useful but can't tell the principle. With the development of science, this mysterious veil will be unveiled one day. Most of Maoshan's fortune-telling is deceptive, but some people can calculate it accurately. Although I am from Maoshan, I have never experienced fortune-telling personally, and I am not in a hurry to talk nonsense.
