《太平广记·卷四百九十五·杂录三》
李抱贞说： 你只要说选择哪天在球场上焚身，我事先在刺使住宅里挖一条地道和球场连通起来，等火烧起来，你就偷偷地从地道里出来。 
抱贞曰： 但言择日鞠场焚身，谋当于使宅凿一地道通连。俟火作，即潜以相出。 
Li Baozhen said, “Tell people that you will burn yourself to death at the sports field on a certain day. I will dig a tunnel in advance from the prefectural governor’s mansion to the sports field. When the fire starts, you can secretly escape through the tunnel.”
