[1] Sometime in the third century, Zhang Zhao recommended Yan Jun to serve under the warlord Sun Quan, who controlled the territories in Jiangdong.
Yan Jun thus recited "The Scope and Meaning of the Treatise", the opening paragraph of the Classic of Filial Piety.
After Sun Quan approved, Zhang Zhao recited "The Service of the Ruler", another paragraph in the Classic of Filial Piety.
[6] Liu Ying (劉穎), a scholar from Guangling Commandery (around present-day Huai'an, Jiangsu), was an old friend of Yan Jun.
[7] After some time, Sun Quan recalled Yan Jun back to service and appointed him as the Prefect of the Masters of Writing (尚書令).
[9] Yan Jun wrote two books – Xiao Jing Zhuan (孝經傳) and Chao Shui Lun (潮水論).
His discussions with Pei Xuan (裴玄) and Zhang Cheng on the historical figures Guan Zhong and Ji Lu were also spread around.
