《资治通鉴·晋纪·晋纪三十八》
每条船上只留一二个人，停船的岸上立起六七面旗帜，旗下放置战鼓，告诉留下的人： 估计我们就要到江陵城时，你们便不停地擂起战鼓，做出后面好像还有大部队的样子。 
舸留一二人，对舸岸上立六七旗，旗下置鼓，语所留人： 计我将至城，便鼓严，令若后有大军状。 
Only one or two people were left on each ship. Six or seven flags were erected on the shore where the ship was moored, and war drums were placed under the flags to tell those left behind: When we are estimated to be about to arrive at Jiangling City, you will keep beating the war drums, making it look like there are still large troops behind.
