Sending the celebratory message will cause fireworks to explode across your screen, with the effect given a red and gold Chinese-themed touch.
The secret feature follows a similar trick earlier this that sent colourful fireworks across your iPhone's screen when sending a 'Happy New Year' greeting.
It's not just the sender that's treated to this explosive animation, either.

As well as hidden features you can access, your iPhone also hides a number of secret features that are only accessible if you jailbreak your phone.
