《太平广记·卷四百五十五·狐九》
有个叫王知古的人，是东诸侯的贡士，虽然涉略过儒家学说，却多次没有被礼部擢为进士，于是回家去到山水之间游玩，把击球喝酒当做正事，在南邻和北里之间到处游玩，到这时才有人把他介绍给张直方。
有王知古者，东诸侯之贡士也。虽薄涉儒术，而数不中春官选，乃退游于山川之上，以击鞠挥觞为事，遨游于南邻北里间。
There was a man called Wang Zhigu, a tribute scholar from the east. Despite his knowledge of Confucianism, he had repeatedly failed to be selected as a "jinshi" (a successful candidate in the imperial civil service examination), so he resigned and travelled the mountains and rivers. He spent his days drinking and playing polo, wandering between the southern and northern suburbs, before finally being introduced to Zhang Zhifang.
