The Sword Testing Stone is one of famous stones in Huqiu. It is said that in Spring and Autumn Age (770 BC-476 BC), He Lv, the king of Wu Kingdom, in order to control the southeast of China, he ordered Mo Ye and his wife—a most well-known couple specialized in sword casting at the time to cast swords. After finished, the couple took the sword to Huqiu and dedicated it to the King He Lv. For testing the sword, the king flung the sword toward the stone, and momentarily the stone split into two pieces. It is common to know that no one could use a sword to split such a huge stone into pieces how sharp the sword it is. As a matter of fact, the stone is a tuff formed in volcano eruption, and after weathered day by day it cracked and formed a line, which looks like it is cut by a sword.
