新年快乐 (Xīnnián kuàilè) is a phrase that means "Happy New Year" in Chinese. Here are the lyrics to a popular Engpsh children's song that you can sing to celebrate the New Year:

Happy New Year, happy new year
We've been waiting for this day to come
We'll all be happy and have lots of fun
It's a new year, it's a new year

We'll ring in the new year with lots of cheer
We'll dance and sing and shout hooray
We'll make lots of noise to chase all the blues away
It's a new year, it's a new year

We'll start off the new year with a smile
We'll make resolutions and walk that extra mile
We'll be kind to others and happy all the while
It's a new year, it's a new year

So let's all have fun and make the most of it
Every day and every minute
We'll make new friends and we'll fit right in it
It's a new year, it's a new year

Happy New Year, happy new year
We've been waiting for this day to come
We'll all be happy and have lots of fun
It's a new year, it's a new year!
