It's no problem to learn Feng Shui from books. But it's not.
1. Seeing Feng Shui depends on learning from teachers besides books. Without the guidance of Yin and Yang teachers, others will not believe that you are self-taught in this field.
2. Yin and Yang teachers have many taboos, one of which is that women are unclean, and seeing the pulse will break the pulse phase, so Mr. Feng Shui always tries to avoid women when setting the pulse phase, except for little girls.
3. Women are yin and men are yang. Feng Shui can't flourish, so Mr. Feng Shui has always refused to accept female disciples.
4. There are many other taboos. Witchcraft has no such restrictions, so there are many witches in history.

Viewpoint 2:
Women are easy to attract yin. Looking at feng shui everywhere, you will inevitably encounter a lot of yin and filth. Women are not fit to be feng shui masters. Men are yang and have stronger resistance. Seeing feng shui requires climbing mountains and wading, which requires a lot of physical strength, not a woman's job.
Like to learn easily, women can learn fortune telling, horoscopes, facial expressions and so on. It is very suitable for women to look at their faces, because women themselves have sensitive characteristics of observing words and observing colors.
