In ancient China, during the Tang Dynasty, Chang'an was a bustling metropolis full of life. New and unusual things constantly appeared: treasures from the West, exquisite handicrafts, and a dazzling array of food and drink. The streets were filled with merchants hawking their wares, and countless visitors thronged through the crowds. Chang'an had become a center for rare and unique treasures. However, behind this splendor was also a fiercely competitive market. The constant influx of novelties presented great challenges to merchants. To attract more customers, they went to great lengths to present ever more original and unusual products. The city's artisans were masterful in their skill, constantly inventing impressive works of art. This constant stream of innovation not only enriched people's lives, but also propelled economic progress.
