Definition

千金难买一笑

Literally means:

smile more expensive than a thousand pieces of gold

Actually means:

it is hard to win the heart of sb

You can't buy a smile even with a thousand pieces of gold. In the past, one may spend a lot of money, but still couldn not find the favor with a great beauty. Now this phrase indicates that it is extremely difficult to win someone's heart or make that person happy.

花费千金也很难买到一笑。旧时指花费很大的代价也不容易得到美人的欢心。现指获得某人的欢心或见到某人的欢笑十分不容易。

Example
