《资治通鉴·晋纪·晋纪三十四》
姚兴想让姚平拚死力战突围出来，而姚平则盼望姚兴能向北魏的包围圈发动进攻，导引、接应他们出来，因此，彼此双方只是叫喊呼唤交相应和，却都不敢逼近北魏的重围。
兴欲平力战突免，平望兴攻围引接，但叫呼相和，莫敢逼围。
Yao Xing wanted Yao Ping to fight desperately and break out of the encirclement, while Yao Ping hoped that Yao Xing could launch attacks on the Northern Wei encirclement, guide and meet them out, so both sides just yelled and called out to each other, but neither dared to approach the Northern Wei encirclement.
