《宋史·列传·卷二百二十一》
徽宗因天旱祈雨，每每派小黄门拿着纸去求王仔昔的画，看他的意见。一天，小黄门又来求画，王仔昔很快画好篆符，并认真地写上 焚此篆符做成汤，用它浇和洗 。
帝以旱祷雨，每遣小黄门持纸求仔昔画，日又至，忽篆符其上，仍细书 焚符汤沃而洗之 。
Emperor Huizong prayed for rain due to a drought and repeatedly sent minor eunuchs to Wang Zixi to ask for a painting to see what he thought. One day, a minor eunuch came to ask for a painting and Wang Zixi quickly finished painting a symbolic character and seriously wrote on it to burn this symbolic character to make soup; use it to bathe and wash with.
