Introduction to the Sword Testing Stone: There is a stone pillar hanging down near the river in Fubo Mountain. It is thick at the top and thin at the bottom. There is a gap of more than an inch at the bottom connected to the ground. It seems to have been split open by a sword. It is a miraculous workmanship. Legend has it that it was caused by General Fubo's sword test, so it is called the sword test stone.
