The song was very popular at that time among children, but not all grown-ups ( 成年人 ) knew it. The girl was very poor. Once her friends invited her to a little child's birthday party. She felt happy but sad because she had no money to buy a present for him. Finally she decided to sing the song Happy Birthday. in the melody (曲调) of Good Morning to You for the little boy. When her friends heard the song at the party, they were very happy. "How wonderfully she is singing!We have not heard this song before. It's a special present," said someone.
