Flower day: Thousands of people went to the Thang Long royal citadel in Ha Noi at the weekend to see the beauty of cherry blossoms at the 2015 Japanese Cherry Blossom Festival. The event was one of the key activities to celebrate the South's Liberation and National Reunification Day on April 30, and mark 42 years of the two countries' diplomatic ties. During the event, visitors had a chance to enjoy Yosakoi traditional dance, cosplay and martial arts performances, and an introduction to special Japanese dishes. — VNA/VNS Photo Chi Toan
