The lyrics of "Where Has the Time Gone" are that after Chen Xi celebrated her mother's 60th birthday, she saw that her mother had "spent half a lifetime of food, rice, oil and salt, and in the blink of an eye, all that was left was wrinkles on her face." This kind of response The feeling of time passing by unconsciously made Chen Xi write the lyrics in one go. After Chen Xi composed the lyrics, Dong Dongdong immediately composed the music.
