Final answer:
Historical accounts of monks like Lokaksema and Xuanzang show the extensive Kushan trade network, which facilitated not just economic but also cultural and religious exchanges along the Silk Roads.
Step-by-step explanation:
The extent and diversity of the Kushan trade network can be inferred from the historical accounts of figures such as Kushan monk Lokaksema and Chinese traveler Xuanzang. Lokaksema's travels to China for translating Buddhist texts and Xuanzang's journey to India for original scriptures highlight the extensive cultural and religious exchange along the Silk Roads. Xuanzang's travel, as depicted in the popular novel Journey to the West, suggests a blend of authentic pilgrimages, cultural interactions, and mythologized adventures that defined the era's exploratory and spiritual quests.
