Put a brick on the roof and a board stand on the brick. What's the point?

Hello, Feng Shui says that the roof is made of bricks and boards, which means that the owner lives peacefully because the house is made of bricks and wood. After the completion of the new house in Meizhou, Guangdong Province, it is still heavy. Now there are stone lions on the roof, which are used to exorcise evil spirits. Hope useful to you
