《北史·列传·卷三十二》
兄弟光伯身遭横祸死去，匆忙间做了一口松木棺材埋葬。你们也可为我做一口松木棺，让我活着能看到它。 
弟顷横祸，权作松榇，亦可为吾作松棺，使吾见之。 
My brother Guangbo met with an accident unfortunately and passed away. A simple coffin made of pine wood was hastily made to bury him. You all may also make me a pine wood coffin so that I can see it while still alive.
