简介：——On the plain outside the north gate of Jinzhou, there are countless trenches. The Ming army dug at least three trenches. Each trench was about one foot wide. In front of the trench, there was a horse-blocking ditch dozens of steps wide. Outside the horse-blocking ditch, there were hundreds of ditches. The steps are densely packed with small potholes, used to prevent shield vehicles from approaching quickly.
