Zhang Lin
It was said that in subsequent confrontations where Gao Pian had victories over Huang Chao, Bi Shiduo was a major contributor to the victories, along with Liang Zuan. Gao thus treated him well. After Gao was transferred to Huainan Circuit in 879, it appeared that Bi followed him there, as Bi was referred to as a Huainan officer in summer 880. By that point, the tide of war had turned against Gao, as Huang had killed Zhang Lin in battle and was advancing north, approaching Huainan's capital Yang Prefecture (). Bi, warning him that Huang's intentions were to further advance north to ravage the center of the Tang state, suggested that Gao launch another attack to intercept Huang. However, Gao, distressed by Zhang's defeat and death, did not make any attempt to stop Huang, who subsequently continued his advance toward the eastern capital Luoyang and the imperial capital Chang'an.
