Im more and more surprised by the evolution of chinese language...
My last surprise was when my students told me "Oh my Lady Gaga" ! i said "sorry ? Oo "
They : "you don't know ?!"
Me : "Lady gaga, yes i know thanks, but what do you mean.."
They : "Oh my lady gaga it's the new expression !"
Me : " --' hao ba"
Anyone could bring some bright light to my mind and explain to me WHY ? eheh
