Coal in geomantic omen

A little bad. From the perspective of feng shui, in this case, opening the balcony will lead to mildew. From a scientific point of view, when you open the balcony door, the coal ash will come in. When you see the coal pile, you will think of coal: after a long time, you will feel that you will be unlucky or something. The solution is also simple. The balcony can be used as a green place, because plants have many functions, such as purifying the environment, absorbing toxic gases, adjusting humidity and releasing oxygen. They can also make people feel energetic and keep your attention on the coal pile.
