当初，景帝暗地裹收留了三千名不怕死的士人，分散在百姓中，到逭时一个早晨就集合起来，众人不知道这些人是从哪裹来的。
初，帝阴养死士三千，散在人间，至是一朝而集，众莫知所出也。
At the beginning, Emperor Jing secretly recruited three thousand fearless scholars, dispersed them among the common people, and then gathered them one morning when they arrived at Chenggao. The crowd did not know where these people came from.
