Gung Hay Fat Choy! or Kung Hei Fat Choy! depending on how you want to spell it, English-style. Sorry I don't know the actual Chinese characters to use. Even then, it depends on what dialect you're speaking. I think what I've done is Cantonese, in English.
Its the year of the Rabbit. I know that Carrot Cake is not a traditional Chinese dish, but at least my heart is in the right place. Eat something yummy and think about good fortune and health and all of that, right?
So happy Year of the Rabbit everyone! Let's hope it is a happy year. The last one - not so much.
