Well,that's really interesting.
In northern China,the weather is so cold in winter,people there always make the ice sculptures, too.
All kinds of the ice sculptures are laid out and shown to visitors,some are like dragon(it's the symbol of China),some are the characters of history stories or fairy tales.
People sometimes put the lights into the art pieces so that they can be more beautiful at nights.
I think the carved candles can also be very nice.
