2 years later, the Saint Giong festival in Phu Dong, Soc temple and Xoan singing of Phu Tho province became intangible cultural heritages of humanity in urgent need of protection. In 2009, UNESCO also recognized the worship of Hung Kings and southern amateur singing. Late last year, the Vi Giam folk singing of Nghe An and Ha Tinh province became an intangible cultural heritage of humanity. It is popular among the locals in central Nghe An and Ha Tinh provinces. They sing Vi Giam to lull their babies to sleep or while they are working in the field. Vi Giam lyrics praise respected values, the tradition of respecting parents, faithfulness and devotion to others as well as treating each other with respect. Associate Professor Nguyen Chi Ben said:“The vitality of Vi Dam folk songs is reflected in their popularity, from lullabies for babies to fishing chants. These folk songs are often sung with the accents of the Nghe An and Ha Tinh regions. This feature makes Vi Giam live long among the local community but makes it hard spread beyond the region”.
