Perhaps the best known of all the works of Po Chü-i is a narrative poem of some length entitled “The Everlasting Wrong.” It refers to the ignominious downfall of the Emperor known as Ming Huang (A.D. 685-762), who himself deserves a passing notice. At his accession to the throne in 712, he was called upon to face an attempt on the part of his aunt, the T‘ai-p‘ing Princess, to displace him; but this he succeeded in crushing, and entered upon what promised to be a glorious reign. He began with economy, closing the silk factories and forbidding the palace ladies to wear jewels or embroideries, considerable quantities of which were actually burnt. Until 740 the country was fairly prosperous. The administration was improved, the empire was divided into fifteen provinces, and schools were established in every village. The Emperor was a patron of literature, and himself a poet of no mean capacity. He published an edition of the Classic of Filial Piety, and caused the text to be engraved on four tablets of stone, A.D. 745. His love of war, however, and his growing extravagance, led to increased taxation. Fond of music, he founded a college for training youth of both sexes in this art. He surrounded himself by a brilliant Court, welcoming such men as the poet Li Po, at first for their talents alone, but afterwards for their readiness to participate in scenes of revelry and dissipation provided for the amusement of the Imperial concubine, the ever-famous Yang Kuei-fei. Eunuchs were appointed to official posts, and the grossest forms of religious superstition were encouraged. Women ceased to veil themselves as of old. Gradually the Emperor left off concerning himself with affairs of State; a serious rebellion broke out, and his Majesty sought safety in flight to Ssŭch‘uan, returning only after having abdicated in favour of his son. The accompanying poem describes the rise of Yang Kuei-fei, her tragic fate at the hands of the soldiery, and her subsequent communication with her heart-broken lover from the world of shadows beyond the grave:-- ENNUI.--_His Imperial Majesty, a slave to beauty, longed for a “subverter of empires;”[15] For years he had sought in vain to secure such a treasure for his palace...._
