I want to ask a question about Feng Shui. Can't you put up posters and pictorial on the bedroom wall?

As long as the photos are not placed in the worst position in the whole room, the others have nothing to do with feng shui. For example, the enlarged wedding photos hanging on the wall are not as big as the poster photos.

Many unlucky things happen in other people's homes for many reasons, which are not necessarily related to Feng Shui.
