老话

zhōng guó yǒu jù lǎo huà yǒu zhì zhě shì jìng chéng

中国有句老话：有志者，事竟成。

There is an old Chinese saying that where there is a will, there is a way.

nà shì lǎo huà

那是老话。

It's the old story.

zhèng rú zhōng guó lǎo huà suǒ shuō

正如中国老话所说

as the Chinese saying goes

tā men tán de zhè xiē lǎo huà xiàn zài de nián qīng rén dōu bù dà míng bai le

他们谈的这些老话，现在的年轻人都不大明白了。

What they are saying about the old days is incomprehensible to young people.
