At the same time, the north belongs to the gate of hell in metaphysics, and more yin will come in when the window faces north. Moreover, in Feng Shui, kitchens and toilets are also shady places. So it is not surprising that Okumo likes to come.
The solution is to clean the kitchen often and keep it ventilated and transparent. You can also put or hang some feng shui objects on your window or windowsill to ward off evil spirits and reduce this influence. You can hang a gossip mirror, but it's not good for other people's homes, unless there is no one across the window. You can also hang a polished animal head or Zhong Kui. This can reduce the adverse effects of windows facing north. Together, we can reduce the accumulation of Yin Qi in the kitchen.
