Lu Jing's mother was Zhang Cheng's daughter. He married Sun He's daughter, who was born to another daughter of Zhang Cheng. Hence, both Lu Jing and his wife were Zhang Cheng's maternal grandchildren. Lu Jing's mother was also related to Zhuge Ke and she was sent into exile after Zhuge Ke and his clan were exterminated in a coup in 253. Lu Jing was thus raised by his grandmother. When his grandmother died, Lu Jing mourned her for three years. Lu Jing served as a Cavalry Commandant (騎都尉) and received the title of "Marquis of Piling" (毗陵侯). He was later promoted to Lieutenant-General (偏將軍) and served as the Commandant (督) of Zhongxia (中夏). Lu Jing was known to be studious and he wrote over 10 volumes of a book. Like his elder brother Lu Yan (陸晏), Lu Jing was also killed in action during the Jin conquest of Wu in 280. He was 31 years old (by East Asian age reckoning) at the time of his death.
^ abcThe Sanguozhi mentioned that Lu Jing was 31 years old (by East Asian age reckoning) when he was killed during the conquest of Wu by Jin in 280. Quote from Sanguozhi vol. 58: (癸亥，景亦遇害，時年三十一。) By calculation, Lu Jing's birth year should be around 250.
