The community 15 building is separated by a river, and the kitchen and study in the north can see the ancestral hall from the side (not directly opposite), okay?

This problem involves the issues of culture and personal beliefs. In some cultures and beliefs, people may think that it is unfavorable to have direct or indirect contact with ancestral temples. But in other cultures and beliefs, this may be regarded as an auspicious sign, because the river may be regarded as a symbol of prosperity.

From the point of view of architecture and planning, if the room in this location can see the ancestral hall from the side, it may have better vision and lighting. In addition, because it is on the 15 floor, it also has good ventilation and air quality.

Generally speaking, this is a complicated question, and there is no simple answer. If you feel uneasy or uncertain about this problem, you can consider consulting some professional Feng Shui masters or local experts in culture and beliefs to get more specific advice.
