In 913, when Li Cunxu the Prince of Jin attacked Yan, Lu Wenjin surrendered to Jin, and, because he surrendered early, was given the title of prefect of Shou Prefecture (壽州, in modern Lu'an, Anhui) — purely an honorary post as Jin did not then control that region. Li Cunxu assigned Lu to serve under his younger brother Li Cunju () the military prefect of Xin Prefecture (新州, in modern Zhangjiakou, Hebei).Zizhi Tongjian, vol. 268.
