Raising roses on the balcony is very important for feng shui.

It depends on the location. Generally, this kind of thorny flower can be placed in the weak part of the mountain star, which can help people and make people healthy. If you put it in the wrong place, it will easily make people lose their temper. Similarly, the fish tank should be placed in a rich position. Modern balconies are generally empty, and it is ok to put some hard plants just to cover up the sense of suffocation.
