오초칠국의 난
Li Guang first distinguished himself during the Rebellion of the Seven States, where he served under the Grand General Zhou Yafu. However, Emperor Jing was unhappy that he had accepted a seal given by Liu Wu, Prince of Liang, Emperor Jing's brother; Emperor Jing had been wary of the Prince of Liang, as Liu Wu had ambitions to place himself as Emperor Jing's successor, over Emperor Jing's own sons. This stance was also supported by Empress Dowager Dou, their mother. Thus, Li did not get promoted to a marquisate despite his anti-rebellion achievement.
