Why doesn't my family want me to learn Feng Shui Yin Yang?

The reason why people don't want to learn Feng Shui is because people think that Yin and Yang Feng Shui is weird and awkward, which easily leads to bad things. In fact, whether it is Feng Shui or Yin and Yang, these are all part of Yijing Shushu, which belongs to the category of Chinese studies. You can study by reading, but you should read the Book of Changes first, and then do academic mathematics, otherwise you will easily go astray.
