In the market of Huofu, in Wanzai County, there was a beggar surnamed Guo, whose left hand and both feet were all twisted upwards. This only allowed him to scrape along the ground leaning on a staff held in his right hand, so people called him ‘Scrape Guo’. His mother was elderly and suffered from arthritis; his younger brother suffered in the same way. Scrape went out to beg on the first and fifteenth day of each month. The people of the market all felt sympathy for him and treated him generously, so he was able to support both mother and brother, gathering a month’s worth of provisions, and he went on like this for eighteen years without resentment. In the winter of the second year Yuanzhen (1296), he encountered a Daoist who, seeing his extreme poverty, and his voluntary support for mother and younger brother, he then took five balls of medicine and gave them to Scrape, saying: “If you take my medicine, your long-standing trouble will immediately be resolved.” Scrape took them as instructed, and his hand and feet were then as normal. Not having expected such healing of his illness, he no longer had a reason for his begging, and people were no longer generous to him. Just as he found himself in dire need, he again encountered the same Daoist. Scrape thanked him, and entreated him, saying: “When I received the kind grant of medicine, I happened to forget that my mother is ill; not having shared it with her, my mother now remains  ill.” The Daoist gave him five more medicine balls; his mother took two balls, and it was as if her illness had vanished. He still had three balls, and this came to the attention of a wealthy person living near the village who suffered from the same condition. The rich person spoke to Scrape: “It is said you have three pellets of a wonder drug; I will buy these from you for one ingot’s worth of paper money.” Scrape replied that he did not want to accept money, but did want to relieve his condition, and, if he could supply the needs of their three mouths for life, he would happily give him the medicine. Afterwards, when the effect had been demonstrated, the wealthy person kept his word and supported them.
It can only be that Scrape Guo’s single-minded filial piety led him to encounter this immortal and benefit from boundless good fortune. Why, if a beggar can devote himself in this way, others should certainly examine their own conduct.
Anon., Huhai xinwen yijian xuzhi, 後1.145-46 (Tale 255):
萬載縣獲賦市，有丐者姓郭，左手及兩足皆反掌於上，止得右手拄地擦行，人遂名以「郭擦」。母老病風，弟病亦然。擦每月朔望出丐，一市人皆憐而惠之，遂得養母及弟，僅得一月之食，如此者十八年無怨。元貞二年冬，遇一道人，見其貧苦，又甘心養母與弟，遂與藥五丸與擦，云：「汝服吾藥，宿疾頓可。」擦如教服之，手足隨即如常。不料疾愈，無可託辭以丐，而人亦無惠之者。方窘急間，又遇元道人。擦謝之，且祈之云：「向蒙惠藥，偶忘母疾，未曾分與，今母尚  病。」道人再以五丸與之，其母服兩丸，其疾如失。尚餘三丸，適為里近富人所知，其病亦同，富人與擦云：「聞汝有妙藥三丸，以鈔一錠與汝回贖。」擦應言不願受鈔，願病安，三口乞終身供給，遂以藥授之。後果效，富人守信供給之，得非郭擦一念孝悌，獲遇神仙以受無窮之福。吁！丐者而處心如此，人亦可以自反矣。
