《周书·列传·卷十一》
原先突厥军队虽已撤退，但仍驻扎在齐国境内，重新聚集各部落兵马，调动了全国的兵力一齐来到，飞速行军，从几路一同推进，相约在仲冬，会师于并州、邺城。
故突厥班师，仍屯彼境，更集诸部，倾国齐至，星流电击，数道俱进，期在仲冬，同会并、邺。
The original Turkish army had already retreated, but they remained駐扎 within the boundaries of the Qi state, where they once again gathered armies from various tribes, and mobilized the armed forces of the whole country to come together. They marched swiftly and advanced along several different routes, agreeing to meet in Bingzhou and Yecheng in the middle of winter.
