Fishermen wait after putting the net in the ice-covered Hulun Lake in Inner Mongolia autonomous region, Dec 26, 2016. Hulun Lake, one of the five largest freshwater lakes in China, has an area of 2,339 square kilometers. The winter fishing as a tourism business usually starts when the temperature goes as low as minus 20 degrees Celsius. To save the fishing industry and the marine environment, only 1,000 tons of fish can be caught in the area since the winter fishing ban came into place in 2014.[Photo/Xinhua]
