Final answer:
The people of Ta-hsia traded with Ch'iung and Shu to obtain goods, participating in a historical trade network facilitated by a diverse range of traders and influenced by state regulations and taxes.
Step-by-step explanation:
The people of Ta-hsia obtained goods from Ch'iung and Shu primarily by trading with them. This exchange was part of a complex network of trade that existed throughout ancient empires and city-states. The historic trading practices involved peddlers, shopkeepers, wholesalers, and merchants, all contributing to a burgeoning market economy. This distribution network was crucial for the dissemination of goods which ranged from basic commodities to luxurious items like silk and porcelain.
Moreover, historical records indicate that various states and governments facilitated and regulated trade by taxing merchants, controlling market prices, and at times engaging directly in commerce, raising questions about the role of the state in economic affairs. Empires controlled and taxed trade routes like the Silk Roads, essential for the movement of goods across vast distances.
