厳復
In 371, after having destroyed Former Yan in 370, Fu Jiān sent messengers Liang Shu () and Yan Fu () to Former Liang, along with the previously captured Former Liang general Yin Ju () and a letter from Wang Meng, in which Wang tried to intimidate Zhang Tianxi into submission. Impressed with Former Qin's show of force, Zhang Tianxi became fearful and apologized, again submitting himself as a Former Qin vassal. Later that year, however, fearful that Former Qin had based large number of troops at his borders, he built an altar west of the capital Guzang (姑臧, in modern Wuwei, Gansu) and had his subordinates pledge an oath both to himself and to Jin, and then tried to petition the paramount Jin general Huan Wen to jointly attack Former Qin with him. (Huan's reaction is unknown, but no campaign was actually carried out.)
