I want to ask, the well faces the window, but it is not in the middle. A little off center. What is Feng Shui?

In geomantic omen, water gathers shade, representing wealth. Well is running water, which is the bureau of making money and also has the effect of gathering shade, but it depends on the overall pattern of the house. Different positions represent different meanings. If the impact is not great, don't worry too much. If there are some negative effects, then open this window less and put some feng shui ornaments in the room.
