In Gushi, in the old society, homeowners paid great attention to the decoration of the roof when building a house. In the middle of the roof, a simple military attache should be set up. It is said that this military attache is the immortal Jiang Ziya. Legend has it that after Jiang Ziya became a god, he was given an official position and had to sit outside. But when the gods see it, they all worship it, so there is a saying that "Jiang Ziya is here and the gods avoid it".

Due to different local customs, other places in southern Henan have different sayings, which can be summarized as "five ridges and six beasts". That is, the ridge bricks of houses are basically ceramic carvings, and the animals carved are tigers, lions, dragons, deer and sheep; Carve fish or pigeons and cranes on the two-room roof; Above the main entrance are carved beasts such as tigers and lions. Carving animals on the roof proves that the owner is rich and symbolizes peace, auspiciousness, wishful thinking and longevity. Of course, small families are not so imposing when building houses. They use "Moon Hee" instead of Wu Ji. The so-called Wen ridge is a kind of unmodified ridge tile or clay covering it, also called "loach ridge".
