It is a masterpiece in Kaohsiung International Steel & Iron Sculpture Festival 2012. The snow ball is sculptured by Mr. Liang, Jen-Hung. He grew from a farmer’s family. As same as many youths in 1970’s, he was yearned for industrialized city life. However, Mr. Liang is willing to return to rural life in recent years. The meaning of sculpture is to present that the higher industrialization, the risk to environment will be accumulated as a snow ball. The risk will become bigger and bigger.
