It is natural to pay attention to Feng Shui when choosing a house, and if there is a cemetery behind the house, this is not necessarily an unlucky sign.
When most people choose a house, except for commercial housing in the city, they mostly demolish and rebuild on their own homestead. But there are some homesteads with a long history, so naturally there will be some older and unattended graves.
Everyone is very taboo about graves and dead people. There is a grave behind the house, which is not an unlucky sign. Because the ancients were very particular about choosing cemeteries. Most cemeteries are located near mountains and rivers, which shows that the back of the house is very solid. So it doesn't matter if the cemetery is behind the house, but if it is in front of the house, it is quite unlucky.
You must know that graves belong to the Yin House. The Yin House itself is the place where the dead live, and it is a place with extremely heavy Yin energy. There are even lonely souls and wild ghosts in some cemeteries, which can easily lead to the Yin House. The internal Feng Shui is deeply affected, and it will also cause family members to often see some unclean things, and often be haunted by ghosts, etc.!
