What song was it when you lied like that before?

What you want to ask is what are the lyrics that lied to your mother before? It's the past. This is the lyrics of the song "Once upon a time" sung by Xiaoqi. Once upon a time, I lied to my mother and crossed mountains and mountains just to hug you. The whole song is a review of the singer's emotional experience. The emotional tone of the song has a green feeling in front of the main song, and the chorus has a mature voice with a little regret.
