So, a chinese friend of mines birthday is coming up pretty fast, and since it will be almost one year of friendship I am thinking of sending him something nice.
We're always only speaking english, though we've said many times he should teach me chinese (mandarin), but I think he'd enjoy it more if I'd greet him in his own language.
I don't speak chinese, and I don't trust online translators grammar, so therefor I'm asking anyone who can speak chinese here to please help me.
How do I write "Happy birthday" to my friend?
