I heard that if a Feng Shui master cannot correct the acupoints, the Feng Shui master will become blind. Is this true?

It’s not that you will be blind, but that you will lose your blessings. The blindness is caused by their practicing Kung Fu. Because it is taught secretly, even if you become blind from practicing it, you won’t tell anyone about it. It is said that after practicing this attack, you can see the earth's energy. When practicing, stare at the sun early in the morning until noon. It takes two or three years to practice well if you are fast, and you will lose sight of it if you are slow.
