Answer:
The cultural impact of the East Asian empires in uniting Asia was significant. The main source of cultural impact was the silk road. Trading along the Silk Road supplied the spread of not just goods, but also ideas and culture, notably in the area of religions, Buddhism and art. The spread of religions and cultural traditions along the Silk Roads also led to syncretism. The Xiongnu adopted Chinese agricultural techniques, dress style, and lifestyle, while the Chinese adopted Xiongnu’s military techniques, some dress style, music, and dance. The Silk Road enormously promoted the culture exchanges between China and western countries. Also, it helped establish the great influence of Chinese culture and Chinese history in the world, especially the Han Dynasty culture.
