As an important part of the city's International Ice and Snow Festival, winter swimming has become famous both at home and abroad.
Even when the temperature dropped to as low as -20 C, the extreme cold and strong wind on the frozen Songhua River couldn't stop the enthusiasm of the winter swimming enthusiasts.
The two-day tournament attracted nearly 600 contestants from China, Russia and the U.S.
