"The state of Chu (11th Century BC-223BC) was the first to build a wall, followed by the Qi, Yan, Wei, Zhao and Qin. After Emperor Qin Shihuang unified the six states, he ordered General Meng Tian to connect the existing walls and to extend them further as a front line defense against possible invasion." Is that what u r looking for?
