《汉书·传·韩彭英卢吴传》
之后，韩信派人求见汉王说： 希望再增兵三万人，我请求乘胜北进，征服燕、赵两国，向东攻击齐国，向南断绝楚国的粮道，最后向西与大王会师荣阳。 
信遂虏豹，定河东，使人请权王： 愿益兵三万人，臣请以北举燕、赵，东击齐，南绝楚之粮道，西与大王会于荥阳。 
After that, Han Xin sent someone to see the king of Han and said: I hope to increase my troops by another 30,000, I request to seize the victory and march north to conquer Yan and Zhao, attack Qi to the east, cut off Chu's food supply to the south, and finally meet the king of Rongyang to the west.
