I know it’s often used in old script and such, but there aren’t many other uses. I was always told that my Chinese name meant light/beautiful girl, but I haven’t found anything pointing to that specific definition.
I kind of get it with the radicals especially in 姜, but I don’t know much about 伊 or even Chinese culture. For all I know it’s like “John” or “Emma” and has a forgotten meaning, or none at all.
I’ve just started learning Mandarin, so I thought getting to know my name, 姜伊, would be cool :)
