It was said that Lu Xisheng was studious and was good at writing. He particularly understood the
I Ching, the
Spring and Autumn Annals, and the
Tao Te Ching well, and wrote many commentaries. At one point, he served on the staff of Zheng Yu (鄭愚) the prefect of Shang Prefecture (商州, in modern
Shangluo,
Shaanxi), at Zheng's request. After he left his service under Zheng, he became a hermit in
Yixing. After a long period of time, he was summoned by the imperial government to serve as
You Shiyi (右拾遺), an advisory official at the legislative bureau of government (中書省,
Zhongshu Sheng). It was said that at that time the ruling officials were corrupt, and there had been several years of bad harvests, with the situation being particularly severe in the region of Bian (汴州, in modern
Kaifeng,
Henan) and Song (宋州, in modern
Shangqiu,
Henan) Prefectures. Lu realized the severity of the situation and submitted petitions that warned that these conditions would be prime for the appearance of agrarian rebels, but apparently his petition drew no reactions. The next year, as he warned, the agrarian rebel
Wang Xianzhi started a major rebellion. Lu later served as the prefect of She Prefecture (歙州, in modern
Huangshan,
Anhui).
Emperor Zhaozong heard of his fame and recalled him to the imperial government to serve as imperial attendant (給事中,
Jishizhong). == Chancellorship and after chancellorship ==
