There is a lyric in the song "Purple Yaya", and the last sentence is "Leave the shadow behind". Very similar to the lyrics of the question. It seems that the questioner heard wrong and remembered wrong.
Song: Purple Yaya
Lyrics Jin Linlin
Classical sentiment of composition
Arrange charm notes
A small house singing warm hearts.
Ziya wears a flower clip.
Travel around the world with me.
The dream house is as warm as a picture.
The tree of happiness hangs high
The beautiful scenery along the way came into view.
Love is in my heart.
Smile happily, right?
Thousands of miles to pursue the flowers in your dreams
The blue sky embraces me.
Gently slide down with fine sand in your hand.
Thousands of waves were splashed on the sea.
Who is the concern in my heart?
Beautiful figure with dancing skirt.
Elegant posture is picturesque in China.
Couples have a drizzle on the roadside.
Ya Ya and I will leave the shadows behind us.
Classic mentality-Jin Linlin original
Ziya wears a flower clip.
Travel around the world with me.
The dream house is as warm as a picture.
The tree of happiness hangs high
The beautiful scenery along the way came into view.
Love is in my heart.
Smile happily, right?
Thousands of miles to pursue the flowers in your dreams
The blue sky embraces me.
Gently slide down with fine sand in your hand.
Thousands of waves were splashed on the sea.
Who is the concern in my heart?
Beautiful figure with dancing skirt.
Elegant posture is picturesque in China.
Couples have a drizzle on the roadside.
Ya Ya and I will leave the shadows behind us.
There is no modification. It's just similar lyrics.
Reading "White Clouds Stay" is as fast as "taking pictures".
The problem is: the last sentence is "stay with the white clouds". "Leave a shadow" is the last sentence.
