Happy New Year, everyone!
My Grandmother made me a mug, and she included something from another language on it. I believe it is Japanese Kanji, but it might be Chinese. I would like to note that she is not Asian, and does not know any languages other than English. Can anyone tell me what it mean? Thank you!

(The one on paper is what I think it looks like, but I included a picture from the mug itself in case I am wrong.)
