"Legend of the White Snake" is one of the folk tales widely circulated in ancient China. The tale goes that a white snake named Bai Suzhen came to the human world and married Xu Xian. Unfortunately, their marriage was opposed by a Buddhist monk named Fahai, who believed that the marriage between human and evil spirit could not be allowed. He then kept Bai Suzhen under the Leifeng Pagoda. Many years later, after gaining a Zhuangyuan title (the first place In the imperial examination), Bai Suzhen's son knelt down in front of the Leifeng Pagoda. God was moved by his action and collapsed the pagoda from which Bai Suzhen is freed. Finally，Bai Suzhen reunited with her husband and son.
