舊 - Jiu4 - Old

舊金山 - Jiu4 Jin1 Shan1 - Old Gold Mountain — San Francisco

I don’t know why San Francisco is called “Old Gold Mountain”. And I don’t know if there’s a “Gold Mountain” or “New Gold Mountain”, either. I do know that San Francisco is where JavaOne is going to be, and I know that I’ll be there.

A saying: 喜新厭舊 - Xi3 Xin1 Yan4 Jiu4 - Like New, Hate Old. This is something you say about people when they’re interested in some new friend and bored with the old.
