In 2021, a cold wave hits.
On January 7, the lowest temperature in Jilin City, Jilin Province was close to minus 30 degrees Celsius.
Part of the Songhua River that winds past the city is frozen.
Affected by the Fengman Hydropower Station, China's "mother of hydropower", the Songhua River flowing through Jilin City has not been frozen for many years.
This low-temperature weather also made the "unfreeze" Songhua River rarely freeze, and the surface of the river was cold and cold.
