I have used the proverb that the people over at ChinaPrime tweeted yesterday, as my daily Chinese proverb, today. I will freely admit not knowing its true meaning and where it would be used, but really made me smile when I read it for the first time.
I am thinking it is probably used to describe temptations and how we might not be able to resist them, but we can prevent them taking over our lives.
nǐ wúfǎ zǔzhǐ niǎoérzài nǐ de tóu dǐng fēixiáng, dàn nǐ kěyǐ zǔzhǐ tāmen zài nǐ de tóufa shàng zuò wō.
You cannot prevent the birds from flying over your head, but you can prevent them from building nests in your hair.
If you have a different idea, or know a better meaning please get in touch.
