Answer:
Religion
Explanation:
Trade between the East and West led to the introduction of religions via the world-famous route called the Silk Route. The Silk Road not only increase commodity exchange but also spread cultures. The Silk Road played a significant role in producing ideas from Europe. Buddhism, Zoroastrianism, and Islam were some of the cultural richness of the West, which offered to China during the old times.
One example of the religion lay on the Buddhist cave temples along the Silk Road built as religious shrines and retreats and temples for monks and travellers. Dunhuang observes trade, cultural exchange, and religion from the 4th to 14th century.
