This is the lyrics:
That's a rainbow picked from the rising sun. No one doesn't like your color.
The most beautiful face in the world, no one will miss your face.
Your bright eyes lead me to stay in my dream and look forward to the future.
When I left home, you blew the horn affectionately.
Five-star red flag, you are my pride
Five-star red flag, I am proud of you.
Cheer for you, I bless you.
Your name is more important than my life.
Red flag floating, red flag floating, empty ambition flying higher and higher like white clouds.
The red flag floats, the red flag floats, and the young heart will not age.
