The mother severely criticized her son and ordered him to return the dozens of pieces of oil immediately and make amends to the oil seller. Lv Dongbin was deeply moved by his honesty. He told the boy that there would be a great disaster on the first day of May, and it would be peaceful to hang a gourd at the door, which could avoid the disaster. The kind mother hurriedly told the neighbors the news, and every family hung a gourd on the lintel after hearing the news.
