If over the lintel of a door one finds two knives, it means that this clan has for generations been expert at making knives. Only those families who possess the greatest wealth, in the form of glass beads and shells, are allowed to sculpt these symbols as decorative elements for their homes.
而門楣上刻有兩把刀的，代表他的家族世代都是製刀能手；家族擁有最多象徵財富的琉璃珠、貝殼，才能刻上這些裝飾圖案。
