《新五代史·世家·越世家第七》
水军士兵司马福，多智谋而又善于潜水，就先用大竹竿碰水中的网，淮人听见铃声就拉起网，司马福于是藉机遇网，进入城中，出来也是这样。
水军卒司马福，多智而善水行，乃先以巨竹触网，淮人闻铃声遂举网，福乃过，入城中，其出也亦然。
The water army soldier Sima Fu was resourceful and good at diving, so he first used a large bamboo pole to touch the net in the water. When the Huai people heard the bell, they raised the net, so Sima Fu took the opportunity to net it and enter the city.
