Written by the apocryphal Taoist philosopher Liezi, between 400 B.C. and 300 A.D.
The Earl of Kung-yi was famous among the rulers of the states for his strength. The Duke of T’ang-hsi mentioned him to King Hsuan of Chou, who invited him to court with the highest honors. When the Earl of Kung-yi arrived, the King examined his physique and found him a puny fellow. He was puzzled and asked doubtfully:
“How strong are you?”
