The ice lantern display first appeared one hundred years ago to mark the Lantern Festival in the northern provinces of China. There are two ways to make ice lanterns. One is to fill water into different moulds and then to freeze the water；the taken-out fillings,when connected to electric sources， are lanterns in different shapes. This is a way preferable for making smaller ice lanterns. The other is to cut different figures from great masses of natural ice with tools like axes,saws,shovels,files and so on. The figures may be in the shapes of mountain peaks，pagodas，towers, flowers and animals. When connected to electric sources, they are illuminating lanterns. An ice lantern display is a sea of lights, feast for any visitors' eyes.
