The entry Mat Na Thien Nhien (The Nature's Mask) by Nguyen Manh Hung is one of 39 ideas for improving Viet Nam's urban spaces using the principles of architecture on display at an exhibition in Ha Noi. The event features ideas submitted by young people from all over the country to the Talent Prize 2013 contest, an initiative of the Viet Nam-Denmark Cultural Development and Exchange Fund. The contest is held to encourage the creation of unique and effective ideas that can contribute to improving urban spaces in Viet Nam. The idea considered best will be awarded after the exhibition closes. A subsidiary prize will be given to the idea with the biggest public vote. The exhibition lasts until October 31 at the Tadioto showroom at 9 Tran Thanh Tong Street, Hoan Kiem District. — VNS Photo Viet Thanh
