《北史·列传·卷四十一》
较量拉强弓，梁的使者能拉开两张各有三石力量的大弓。綦连猛便一起拿出来四张各有三石力量的弓，叠在一起一下拉开，超过了梁朝的使者的力量，梁人感叹佩服。
校挽强弓，梁人引弓两张，皆三石；猛遂并取四张，叠挽之，过度。梁人嗟服。
In the contest of pulling strong bows, the envoy of Liang was able to pull open two large bows, each with a strength of three stones. Qilianmeng took out four bows, each with a strength of three stones, and pulled them together at once, surpassing the strength of the envoy of Liang, and the Liang people were impressed.
