The Zhuangzi contains the parable of the one-legged kui pitying the millipede.
Tips
history
Famous from 《庄子·秋水》: 夔怜蚿,蚿怜蛇 — the one-legged kui envies the many-legged millipede, which in turn envies the legless snake. The allegory: no creature's form is "best."
usage
Today 马陆 (mǎlù) is the everyday term for "millipede"; 蚿 is literary. Note: some sources also give a reading wén as a variant of 蚊 (mosquito) — the millipede reading xián is the one meant in Zhuangzi and modern zoology.
