I want to know the answer to the following question:
Which member of the Han Empire was sent to Daqin in AD 97?
All the background I'm provided with is that "A Roman embassy of Emperor Marcus Aurelius (r. 161–180 AD) is recorded in the Hou Hanshu to have reached the court of Emperor Huan of Han (r. AD 146–168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants.". Is that enough to answer the question?
