elizabeth i was referred to as elizabeth i ever since the th century this is absolutely not a modern convention please refrain from talking about subjects you seem not very familiar with as for the chinese case liu bang and xiang yu were commoners and their family names were used with their given names i believe by bc family names were starting to be commonly used in china and if you check the historical records by sima qian he refers to them as liu bang and xiang yu on the other hand the royal family of qin were not commoners and their family name ancestral name was never used you can check the historical records of sima qian he never writes ying ziying he always writes ziying only it is a modern anachronism to write ying ziying it would be like writing louis bourbon instead of writing louis xiv
