How do you write Happy Anniversary in Chinese?
Actually, we don't have the exact equivalent translation to
"Happy Anniversary" as the word "anniversary" contains a lot of
uncertainties (such as anniversary for marriage? anniversary for
important festival?......)
But anyway, I could still offer you the direct word-to-word
translation of "Happy Anniversary", which is "周年纪念日快乐".
Hope this won't disappoint you ;)
