Introduction to the ancient well in Guiling: When the villagers of Liji dug a well here around 1980, they dug it 10 meters underground. This well happened to be dug. When it was built, no one in the village, old or young, knew. Suspecting that it was left by the ancients, the green bricks were laid to the ground, with a diameter 10 centimeters larger than the ancient well. During the cleaning, more than 10 pieces of various pottery utensils were found. Nearby farmers call it "well within a well". Later, experts verified that this well should have been built by the soldiers stationed in the camp to provide water during the Battle of Guiling. The original well was 16.9 meters deep, with gravel at the bottom, water flowing like a spring, and a sweet texture.
