I am making my own invitation cards and feel compelled to inject some Chinese essence into the whole wedding. Hence, the double happiness character will probably be featured over and over in our wedding.
Each half of the symbol is the standard character for happiness, written "hsi" or "xi," and pronounced "she" in Mandarin. Therefore, two "hsi" characters together represents the wish for the two young newlyweds to have happiness together. The double happiness (pronounced "shuang-hsi" in Mandarin) is a special Chinese character used for marital happiness
Being in charge of this wedding has been an adventure in itself and has made me research chinese customs to enrich the experience. Instead of a (western) rehearsal dinner, I will be having a traditional chinese wedding dinner/banquet with the added feature of the customary tea ceremony, which I am sure will thrill my family and David's to no end...but those are things for another post :)
Sometimes I feel lost, though, and wish my mommy was here...
