The Zhan Che (戰車) was a type of war cart designed by Zhang Xue Yan (張學顏), Grand Coordinator of Liaodong based on an older model devised by Li Wen Da (李文達). It was designed to be able to keep up with Ye Meng Xiong's lightweight war cart and was equipped with a leather protective screen, two stacks of rockets and Shen Qiang (神鎗), as well as rows of anti-cavalry spears projecting from all four sides of the cart.
