Final answer:
The Tang dynasty was a cosmopolitan empire known for its cultural achievements, while the Song dynasty was a period of economic prosperity with important technological inventions.
Step-by-step explanation:
The Tang dynasty (618-907) and the Song dynasty (960-1279) were both significant periods in Chinese history.
During the Tang dynasty, there was a cultural flourishing known as the "Golden Age." It was a cosmopolitan empire where people from different parts of the world interacted, bringing influences from Persia, Arabia, and Central Asia. The Tang dynasty was known for its arts, such as calligraphy and landscape painting, and many technological innovations took place during this time, such as paper-making and woodblock printing.
The Song dynasty, on the other hand, was a period of economic prosperity. Important inventions like gunpowder and the compass were made, and the Song were the first to issue paper money. They also established large manufacturing industries, which produced consumer items for a growing market. The population doubled, and extensive waterways were built to support widespread rice cultivation.
