简介：——The shield car is eight feet high and six feet wide. It is made of boards cut down from surrounding trees. Four wooden wheels are installed below. The front guard and top plate are eight inches thick. It can defend against the most powerful turtle dove guns and light artillery of the Ming army. It is also difficult to hurt it. From a distance, it looks like a huge square shield being pushed away as its name suggests.
