Thousands of young people in the capital city of Hanoi flocked to Cau Giay Park for a blood donation festival on September 29.

The event, launched by the National Institute of Haematology and Blood Transfusion and the Hanoi Youth Blood Donation Mobilisation Association, was expected to collect more than 1,000 units of blood.

Chu Hop Nhat, the association’s president, highlighted the scarcity of the O blood group for medical treatment in blood banks across the city.

The festival encouraged people with this blood type to donate as a good deed to the community, demonstrating the tradition of mutual affection and assistance of Vietnamese people, he said.

A wide range of activities were also held during the event, including exchanges between university students, volunteers and clubs in the city, and art performances.-VNA
