Yilin Verse
穿空相宜，利倍我北，循邪詭道，逃不可得，南北望邑，遂歸入室。
Threading empty spaces, finding advantage; profit doubled to the north. Following devious and crooked paths; escape cannot be had. Looking north and south at the town; at last one returns and enters the house.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
