What are the precautions for buying a second-hand house?

1. Look at the terrain. It is surrounded by beautiful scenery, backed by high slopes and with beautiful water in front. The environment is clean and beautiful, and there is no obvious shape when passing through sodium nitrate sand and water. 2. Buildings should not be built on isolated hilltops or water bodies. It is not a good choice to build on the ridge line of a mountain or on a water body. Can't be built under cliffs and so on. 3. Look at the rivers and roads. If there are rivers and roads around the building, it is auspicious. If there is a river or road that bows its head towards the building, it is unlucky to bow its head against the current. It is unlucky for a road or river to go straight to the arrow. 4. See if there are any temples, military and police departments, crematoriums, cemeteries, prisons, shrines, etc. Nearby. Yang Zhai should stay away from such buildings.
