The two villages are close neighbors. Yanshi village was called Wangjiazhuang in ancient times. "Wang Chan's bodhi old zu" is the name of Guiguzi by later generations, and it is one of the pre-Qin philosophers. Gui Guzi is the originator of military strategists (in fact, he is also one of the famous representatives of military strategists), and Su Qin and Zhang Yi are his two most outstanding disciples (see Warring States Policy).
