1. Feng Shui problem: In Feng Shui, the northeast corner is considered as a financial position, so building stairs here may lead to "financial leakage" or "financial loss". If the stairs must be built in the northeast corner, it is recommended to consult a professional feng shui master for guidance and adjustment.
2. Practicality and safety: the location of stairs needs to consider practicality and safety. For example, the stairs built in the northeast corner may affect the layout and lighting of the room. In addition, the stability and safety of stairs also need to be fully considered.
As for whether it is feasible to make two doors in the northeast corner, it also needs to be decided according to the specific situation. If the design of the two doors is conducive to the lighting and ventilation of the room, it may be feasible without affecting the structure and beauty of the whole building. However, before implementation, it is recommended to ask professionals for evaluation and guidance.
