The tiles on the living room floor are arched. Is there anything to say about Feng Shui?

It's just that there is something wrong with the tiles and they need to be repaired.

The emergence of arching may be affected by thermal expansion and contraction and too small joint spacing.

You'd better replace this tile. You can ask a professional bricklayer to replace it.

It is best to replace the same series of tiles with the same model, otherwise there will be differences in patterns and colors.

A school of tiles will answer for you!
