As far as children's songs are concerned, except Chinese children's songs, children's songs of other languages and nationalities can be listened to by babies. For example, the British classic children's song series WeeSing, the German classic children's songs Song of Little Heels, Knutbear, Bruder Jakob (German version of Two Tigers) and children's songs from Japan, South Korea, Russia, Finland and other parts of the world. Besides nursery rhymes, folk songs of different nationalities and languages, such as China folk songs, Japanese Yayue Mongolian Humai Indian music, African music, and music of different religions, such as the Catholic and Islamic hymn "Song of the Gyro", can be listened to by the baby, which can enrich his multicultural experience.
