What are the feng shui taboos for buying a house?

Looking at buildings or mountains, it is unlucky to have tall and flat buildings or beautiful squares, gardens, sharp mountains behind them, a messy and vacant back, sharp lenses, too much pressure, etc. And a weapon-shaped building in front, avoiding pressure and being blocked, with arrows and corners in the house. It's unlucky to shoot and the front is open and the scenery is beautiful. The buildings on the left are generally lucky to be taller than those on the right, and the buildings on the right are generally unlucky to be taller than those on the left, especially those with strange shapes.
