《辽史·列传·卷三》
初时字铎碗，先隶于太祖幕下，曾经生了病，太祖赐予他一樽酒，喝下便痊愈了，辽语酒樽称 撒剌 ，所以下诏让他改字撒剌。
始字铎碗，早隶太祖幕下，尝有疾，赐樽酒饮而愈，辽言酒樽曰 撒剌 ，故诏易字焉。
At first, his name was Duo Wan, and he was a subordinate of Taizu, who fell ill. Taizu bestowed upon him with a jar of wine, which made him recover from the illness. The word for wine jar in Khitan language is Sala, so an imperial edict was issued to change his name to Sala.
