Although the Great River Kingdom was far from the Tang Empire, the two countries had kept friendly diplomatic relations for generations. People in the Great River Kingdom admired Tang culture. They had sent numerous delegations and students to Chang'an throughout the decades. Its political system, architecture, culture and even lifestyle were greatly influenced by the Tang Empire.
Jingdu was the capital of the Great River Kingdom. The city was surrounded by snow mountains. Most houses in the city had black eaves. Flowers bloomed in people's gardens as well as along the rivers. The imperial city set off among the blossoms. It was picturesque.
People living there were very good-looking. They had peaceful and tender smiles and looked persistent and devoted. They wore light colored robes with flowery waistbands. Most of them bore long swords in black sheaths by their waists.
