How can Xuan Kong Feng Shui change the heavenly heart?

If it is a rural house, or other houses, you can open an opening in the center so that the sun can shine in. After 49 days, it will be a change of heart.

If it's a unit house in a city, it can't be changed in the traditional way, so we should redecorate the house, so that the air quality of the house will be changed, which is equivalent to changing the mind.
