苻姚 (The first character has the fanqie 房無 [fáng + wú]; the surname of the Former Qin. The Shiji states: '[Fu] Jian was originally a native of Linwei in Luoyang; because the calamus growing in the pond of his home had anomalous signs, they took Pu [蒲] as their clan surname. Later, when grasses formed the character Fu [付] on his grandson's back, they changed it to the Fu [苻] clan.' The second character has the fanqie 餘昭 [yú + zhāo]; the surname of the Later Qin. From Yao Yizhong down to the reign of [Yao] Hong, it lasted thirty-four years until destroyed by Liu Yu).
