A merchant from the Roman Empire called Qin Lun by the 
Chinese, arrives in Jiaozhi (modern 
Hanoi) and is taken to see 
Sun Quan, king of 
Eastern Wu, who requests him to make a report on his native country and people. He is given an escort for the return trip including a present of ten male and ten female blackish-coloured dwarfs. However, the officer in charge of the 
Chinese escort dies and Qin Lun has to continue his journey home alone.
