Hi, hope all is doing well at this COVID timea. I have a question, my living room is sunken (about 30cm down) compared to other areas of the house, since the natural terrain of my plot is inclined. Some people who visited my house says that this is not good Feng shui. Could you please enlighten me. (Flooding is not a problem in where I live.) Thanks for you answer in advance Regards, Severino
