sorry, i must be stupid cause i didn't catch that , but why?
Xiao means "little" so its a common nickname to call people younger than you, ie Xiao Qing is little Qing
Ohh that's cute, didn't know that. Thank you !
Xiao is also works similar to -chan in japanese for example like yuki-chan. Its a very casual suffix you'd attach to the name someone your close to in a similar or close age~
Thank you translator, I finally understand why every chinese manhua has characters called Xiao, I've never understood before
