《魏书·列传·卷五十八》
这时傅永下葬已经数十年了，棺木被桑枣树根所缠绕，离地面一尺多，很是坚固，便用斧砍去根茎，挖出棺木，上面都已坑坑坎坎了，当时人都很奇怪。
葬已数十年矣，棺为桑枣根所绕束，去地尺余，甚为周固，以斧斩斫，出之于坎，时人咸怪。
At this time, Fu Yong had been buried for decades. His coffin was wound by the roots of mulberry and jujube trees, more than a foot above the ground. It was very strong, so the stalks were cut down with an axe and the coffin was dug out. There were many pits and bumps on it at that time, and people were very surprised.
