Gong Xi Fa Ca! That’s the traditional Chinese New Year greeting that means “wishing you prosperity” in Mandarin. The first day of the Chinese New Year – which begins at midnight on January 23, 2012 – is the most important of Chinese holidays, celebrated by billions in China, and by millions of ethnic Chinese around the world. It’s a celebration that lasts for 15 days, culminating with the Lantern Festival. Each year is associated with one of twelve animals in the Chinese zodiac. For 2012, it’s the Year of the Dragon.
