A two-day winter fishing tourism festival opened here on Saturday, during which 18 inheritors of Chagan Lake winter fishing showed visitors traditional ways of fishing. Winter fishing on ice-covered Chagan Lake dates back to the Liao and Jin dynasties from 10th century to the 13th century in China and was listed into the national intangible cultural heritage in 2008.
