Winter swimmers in Beijing are enjoying one of the last pieces of unfrozen natural water in the city - part of a lake kept unfrozen thanks to the activities of five ducks who swim in that patch.

Zhang Jingzhong, who has been swimming in icy water for 12 years, says it is the ideal way to escape the pressures of daily life.
