功夫

眨zhǎ个gè眼yǎn的de功夫gōngfu，贡gòng特tè就jiù不见了bùjiànle。

In a wink, Gunter was gone.

我wǒ没méi功夫gōngfu吃饭chī fàn。

I had no time to eat.

我wǒ想xiǎng解决jiějué这个zhège问题wèntí，可是kěshì白费báifèi功夫gōngfu。

I tried in vain to deal with the problem.

挺好tǐnghǎo，挺好tǐnghǎo，下一次xiàyīcì再zài花huā点儿diǎnr功夫gōngfu就jiù成功chénggōng了le。

Good, good, next time use a bit more effort and you'll succeed.
