A man of the state of Lu was skilled in weaving hemp sandals while his wife was good at weaving fine white silk. The couple thought of moving to the state of Yue in the south.
"You will be in dire straits," he was told.
"Why?" asked the man of Lu.
"Hemp sandals are for walking but the people of Yue walk barefoot. White silk is for making hats but the people of Yue go about bare-headed. If you go to a place where your skills are utterly useless, how can you hope to do well?"
