《南齐书·志·卷十八》
臣下考定桑字是四十二点，世祖年纪过四十二岁就会登帝位，认为穿木屐是行木德。
臣案，桑字为四十而二点，世祖年过此即帝位，谓著屐为木行也。
My subordinates have determined that the character mulberry has forty-two dots. When the World Ancestor is over forty-two years old, he will ascend to the throne. He believed that wearing wooden clogs was in line with the virtues of wood.
