Yang Liang
After Chen's destruction, Yao Silian served as a military advisor to Emperor Wen's son Yang Liang the Prince of Han. At some point, due to Yao Cha's death, he resigned to observe a mourning period. He thereafter served as a secretary at the government of Hejian Commandery (河間, roughly modern Baoding, Hebei). He requested permission from Emperor Wen's son and successor Emperor Yang to continue writing the histories of Liang and Chen that Yao Cha had started, and Emperor Yang agreed. Emperor Yang further ordered him and another official, Cui Zujun (崔祖濬), to lead a team of scholars in drafting regional maps and histories. He later served as a teacher of Emperor Yang's grandson Yang You the Prince of Dai.
