Students at the Tagore International School sing for Peng Liyuan in Mandarin. The visit is entirely nonpolitical, said Preeti Chadha, director (international relations), Tagore International School. "We have heard that Ms Peng is an exceptional artist and we are thrilled to welcome her," she said. Students of the school have been learning Chinese for the last two years with the help of teachers from a school in Shanghai.
