Happy birthday to you，
Happy birthday to you，
Happy birthday dear [名字]，
Happy birthday to you.
We hope you have a wonderful day
With fun and fun all day long，

With candles to blow out.
You are the best of friends，
And you make us all laugh，
So on this special day，
We want to say HAPPY BIRTHDAY!
We'll keep you laughing always，
With fun and games all day，
So remember this day，
You're the best of all.
Happy birthday to you.
