Mister Lữ goes fishing in the afternoon\nBut then the crocodile suddenly took him away\nIt is easier to find silver and gold\nBut to find a meaningful bond is rarer than most\n\nLullabies (Ru) within the family environment has a hypnotising function, where it's used to ease the child into sleeping. Southern Vietnam (Nam bộ) lullabies was formed and sustained through the many layers of Nam bộ culture. The environmental ecosystem and culture have given it a distinctive form that is expressed through lyrics, melodies, and rhytms.

Mongolian folk songs are divided in three different categories, such as long songs, short songs and the authors’ songs. Folk songs are shorter than other forms of expressions with average durations of one to five minutes, but there is a high volume of them. Thus, restoring, categorising, and digitising folk songs were the most time-consuming tasks compared to others. Within the framework of the project, just under forty-eight hours of songs were restored and digitised.
