tomb, made in the shape of Mount Tie (鐵山) in Eastern Tujue territory and Mount Jishi (積石山) in Tuyuhun territory, under the precedents that the great Han dynasty generals Wei Qing and Huo Qubing had their tombs built in the shapes of mountains in Xiongnu territory to commemorate their victories, be constructed for Li Jing's wife (as Li Jing would eventually be buried there as well). In 643, when Emperor Taizong commissioned the Portraits at Lingyan Pavilion to commemorate the 24 great contributors to Tang rule, Li Jing's portrait was one of the 24. In 644, when Emperor Taizong was set to attack Goguryeo, he summoned Li Jing to consult his opinion. Emperor Taizong stated to him: You, duke, pacified the Wu region [i.e., the lower Yangtze] to the south, cleared the desert to the north, and settled the Murong [i.e., Tuyuhun] to the west. Only Goguryeo has not submitted. What do you think? Li Jing responded: Your subject had, in the past, depended on your heavenly power to give my minor contributions. I am old and my bones are weak, but if Your Imperial Majesty does not look down on me, I am nevertheless willing to go despite my sickness. Emperor Taizong, however, saw that Li Jing was ill and decided not to send him. Emperor Taizong later personally led a largely unsuccessful attack on Goguryeo. Li Jing died in 649—briefly before Emperor Taizong's own death—and was buried with great honor, near Emperor Taizong's own tomb. Works attributed to Li Jing As one of the best generals and strategists of the Tang dynasty remaining undefeated in his career, Li Jing wrote several books about military doctrines. Although most of his work is not preserved today, fractions of them were cited by the Tongdian, an encyclopedia about the historic system of politics in China. One of the Seven Military Classics of China, Duke Li of Wei Answering Emperor Taizong of Tang (唐太宗李衛公問對/唐太宗李卫公问对, Táng Tàizōng Lǐ Wèigōng Wènduì), is a purported dialogue between Li Jing and Emperor Taizong about strategies, policies, and tactics. They criticised The Art of War, Zhuge Liang's strategies book and the New Book of Mengde. The work is attributed to Li Jing, although many modern scholars doubt the attribution, as neither the Old Book of Tang nor the New Book of Tang mentions the work in their biographies of Li Jing.
