Hong Kong: Young children hold Christingles, meaning "Christ Lights", during a festive church service on Christmas Eve in Hong Kong, on December 24, 2013. The services derive from a Moravian custom of distributing lit candles to children on Christmas Eve in order to celebrate Christ, the light of the world. A

Christingle is made of an orange, representing the world, with a red ribbon around it representing the blood of Jesus. Fruits and sweets are skewered onto cocktail sticks which are pushed into the orange representing the fruits of the earth and the four seasons. A lit candle is finally pushed into the center of the orange representing

Christ, the light of the world. (Anthony Wallace/AFP/Getty Images)
