Kungfu = 功夫 [gōng fū]

A baby in a yellow onesie lies on a quilt with fists up and one leg kicking, ready for a fight. That is baby 功夫.

功夫 (gōngfu) means “kung fu,” Chinese martial arts; the English word comes from it. The 夫 is usually said light, even though the drawing marks it fū.

功夫 also means time and effort: 花功夫 (huā gōngfu), to put in effort. Chinese martial arts are also called 武术 (wǔshù).

他会功夫。 — Tā huì gōngfu. — He knows kung fu.

学好中文要花很多功夫。 — Xué hǎo Zhōngwén yào huā hěn duō gōngfu. — Learning Chinese well takes a lot of effort.
