Some people say that the cultural space of gongs originated from the Dongzi culture in ancient Southeast Asia, also known as the bronze drum culture in Southeast Asia. Vietnam's gong culture is characterized by its playing style. Each player carries a drum with a diameter ranging from 25 to 80 cm. Male and female villagers drum 3 to 12 by village. Different arrangements and rhythms cooperate with different ceremonies, such as calf sacrifice ceremony, rice praying ceremony, memorial ceremony and harvest celebration. The gongs in this area are not made locally. They were imported from neighboring countries and tuned to the tone they expected to use.
