VOV.VN - The first phase of the Dong Kinh Nghia Thuc Square renovation has been completed, giving a facelift to the pedestrian area around the iconic Hoan Kiem (Returned Sword) Lake in downtown Hanoi. The square is named after the Dong Kinh Nghia Thuc (Tonkin Free School), a progressive school founded by Vietnamese scholars in 1907 to promote modern education and patriotism.
