Building a house in the countryside these days can't build an east house. It is superstition, but there is still such a saying.

There must be superstition. There is nothing wrong with building the East Palace in geomantic omen. Just pay attention to the environment. If the bedroom window can't face south, then face east. Clean up the sundries near the residence (good for health). If there is a big stone, you'd better get rid of it, or the child may get hurt. It is good to have a tree nearby, but it is not good to have a tree at the door (harmful to health through psychological factors).
