Luring the Imperial Tutor into the Palace

In his old age, Xiao Hanyu looked back on the first half of his life and remembered two people who had shaped it forever. One was his imperial elder sister, who seemed to spend her days drinking and dreaming her life away. The one thing she said all the time was, "When will Hanyu finally grow up? When will he take over my throne?" The other was his Grand Tutor, who warned him every day, "If you don't study harder, your elder sister will keep the throne forever!" Once he finally got the hang of things, his elder sister handed him the throne and went off with the Grand Tutor to travel the land. He was furious. Why had they left him alone to guard this splendid realm?
