In Feng Shui, there is a saying that a house surrounded by a bamboo forest will bring wealth and wealth. However, at the same time, bamboo is a yin plant, so it will not only make people rich, but also cause many illnesses. There is a saying that "more wealth will weaken the body". If you plant bamboo at the "Ghost Gate" in the southwest or northeast, it is more likely to attract Yin spirits into the house. Maybe my colleague said that bamboo cannot be grown due to this consideration.
