The neighbor's house in the east is one floor higher than mine, and there is a road before and after. Who can tell me whether this feng shui is good or not and how to solve it?

If the neighbor is a little farther away, it's not a big problem, just look at the good or bad luck of Luan Tou. If the house next door is close to home (with a small gap of less than three feet in the middle), it is evil and naturally unfavorable. If two gables are connected (or a wall is used), it is a little better. Generally speaking, it means threatening and persecuting.

For reference.
