Winter fishing season has come once again to Chagan Lake in northeast China's Jilin Province. Each winter, Mongolian fishermen brave temperatures of -20 to -30 degrees Celsius, and use a centuries-old technique to catch fish. And because the old fishing method is very time-consuming, each fishing crew can only cast their net once a day. As the fishing season goes on, fishermen will slowly approach the center of the lake where the highest number of fish are typically caught. Join CGTN's Guan Yang and Feng Yilei for a real-time good catch of this ancient and fascinating tradition from northeast China.
