Bilike has never seen a ping-pong ball before. He and his family live without electricity and running water in a solitary tent home among the vast steppe grasslands. The magnificent landscape here has changed little since the days of Genghis Kahn. But life in the middle of nowhere can be exciting for a young boy.
