“Since you don’t have nine older brothers, why are you called Shi?” - wordplay! My favorite to translate. Gah.

Anyway, Chen Shi’s name is a full homophone of the word for ten, and also is how “ten” is spelled in certain situations (on money, for example). It’s not unusual for someone’s name to be a number denoting what child they are - take for example Wang Qi, whose name means “seven”. However, the “shi” in Chen Shi’s name also has a meaning of “picking something up”, which turns out to be the correct interpretation in this case!

And yeah. Surprise General Qiu lore
