I have a pendant with Chinese or Japanese symbol, and I don't know what does it mean.
Could you help me to find an answer?

Thanks for your help

The closest I got was that:

Meaning : serve, attend upon; attendant, servant; samurai

I know, there are a lot of characters, but you'll see it here, though there are not as many meanings given as previously:

Just select the text meaning I typed above and look for it in the first link.

Hope it helped! :)

Please rate my answer if it was of any help. :)
