《元史·列传·卷四十六》
此时，天降大雪，刘万户去慰劳璧之劳苦，酌酒祝贺道 ：经略一到就诛锄强暴，今日之雪实为瑞兆。 
刘大惊，时天大雪，因诣璧相劳苦，且酌酒贺曰： 经略下车，诛锄强猾，故雪为瑞应。 
At this time, heavy snow fell, and Liu Wanhu went to comfort Bi's hard work, poured wine to congratulate him and said: "As soon as the strategist arrives, he will punish the violence. Today's snow is really a sign of auspiciousness."
