Why isn't the ancestral hall floor tiled?

There are several reasons why the ancestral hall floor is not paved with floor tiles:

1. Fengshui reason: The ancestral hall is taller than its own house, which can absorb the open space and popularity in front of the hall, increase the atmosphere and enhance the family's momentum and fortune.

2. Cultural symbol: The ancestral hall is a place for ancestor worship and sacrifice, representing the face and sacredness of the family, so its ground needs to reflect the corresponding cultural symbol. Materials such as green slate are more in line with the ancestral hall, which can better reflect the solemnity and historical sense of the ancestral hall.

Generally speaking, the reason for not using floor tiles is the consideration of geomantic omen and cultural symbols.
