123 goodbye. Lyrics: "Time is too short. We have been together in a hurry for more than a hundred days, and the public will remember it with joy. We don't have to meet every morning and evening. Please don't hold your hand on your lips, mind your mouth, and the public will say goodbye. See all about 123, dear children. The lyrics come from the song Goodbye 123, which is a children's song sung by the singer and can be listened to on Kuwo Music Network.
