Once you wake up from your dream, you will only be left with eternal regrets. Staring eastward, facing the stars, national justice, quarrels in the world, family love, why is she tired of the floating world? She is not only a princess of a country, but also a sword holder who walks in the dark places of the world; he is the proud son of heaven and the pillar of a country, but he only works for one person throughout his life. May we join hands in Changan after the troubled times.
