The Happy Birthday song is one of the world's most popular songs in the world. People around the world sing this song on their birthdays. But do you know the story behind the song?

In 1893, Mildred Hill, a kindergarten teacher from America, wrote a simple tune(曲调), and her younger sister Patty added the lyrics(歌词). They called it Good morning to All. Each morning, teachers sang this song to the children as a welcome song in the class. But when it came out, children across the United States loved this song very much, and they sang it to their teachers every afternoon when they left school.

Lator Robert H. Coleman added a second part to the song. It was the now famous Happy Birthday song. His second part made the song much more popular.
