In the city of Chang'an, Hu merchants and poets were drunk together in the brightly lit Wanjiafang City. Envoys from various barbarians worshiped at the Daming Palace with the clothes of the Celestial Empire. Thousands of scenes surged into the ocean of poetry, creating the most splendid golden age of civilization. A person from later generations who traveled through time stood in the court hall, looked at the grand scene of thousands of people coming to court, and said loudly: "I only hope that the descendants of future generations will not have to learn the language of Yi and Di."
