Event organiser, the Da Nang Sun Flower Foundation, said the performance was part of an annual charity programme that raises money to help poor children with cancer living in Da Nang and Quang Nam province.
It said this year it was hoped to raise VND500 million ($22,000) to support five children aged between three and 13 years.
The five children are being treated at the city’s Oncology Hospital.
According to the Da Nang Association to Support Poor and Disadvantaged Women and Children, more than $28.6 million has been donated from foreign and domestic people to help cancer patients.
