Introduction to the Sword Testing Stone: The mouth of the Yingdie Wind Valley is a sword quenching pool with a roaring waterfall all year round. According to legend, this pool is where Li Babai tempered his sword. There are eight hundred stone statues of Shuo Li quenching his sword beside the Sword Tempering Pond. After the sword was completed, Li Babai once selected a huge stone in the mountain to test the sword. There is still a "sword test stone" split into two sections in the scenic area.
