Dear Master: Most of the time, small taichi is used in 8 aspiration theory according to bagua. In modern time, most of peopleare living in apartment inside the big building, where the big building has many rooms / apartments/ condos. If we live in one of the rooms/ apartments inside the big building, it seems that one room/ apartment is a small taichi of the big apartment building. Can we apply flying star feng shui in the specific room of the big apartment building such as only the apartment section that we live? If the big apartment building has 1000 rooms/ apartments,while 2010 flying star #2 (ill star) strikes in the NE direction, will this star afflict in the NE areas of the big building only or All NE directions of every room/ apartment inside the big building? Which one? Thanks. DV
