Long story short,. I would love to know what this means!
He has a cantonese translations book (presumably for getting in with all those chinese ex's, )and they (the chinese girl who keeps writing " Fay Sor Loh") lived in Ireland if this helps?
I've tried translation pages online, all to no luck.
Many thanks
Update: Thanks very much.. can anyone tell me What Language this is, Please??
