Introduction to the Sword Testing Stone: According to legend, Ye Fashan once refined elixirs in the Baihe Cave and Danjing at the foot of the peak. The elixir became the Testing Sword, and he split the boulder into four. The broken wall was more than 30 meters wide and more than 10 meters deep. It is known as the Sword Testing Stone. , also known as the "Four-Corner Altar". Standing on the back of the sword test stone, you can overlook the entire county of Ou Qingtian: the Oujiang River in the south, dotted with sailboats; the Overseas Chinese New Village and Overseas Chinese Hotel in the east, which are neat and spectacular; The commercial street is busy with traffic. At this moment, I feel cool and refreshing. No wonder many famous people from past dynasties have left their mark here.
