Photo taken on Dec. 28, 2016 shows newly-caught fishes on the Chagan Lake in Songyuan City, northeast China's Jilin Province. Winter fishing on ice-covered Chagan Lake dates back to the Liao and Jin dynasties from 10th century to the 13th century. Today, local fishermen hold a ritual to offer a sacrifice to the lake god before they begin winter fishing. Fishermen here plan to catch 1.3 million kilograms of fish this winter. (Xinhua/Zhang Nan)
