Huge ice blocks were spotted on a river in Huzhong District, China's coldest town when the outdoor temperature was above 20 degrees Celcius.<br /><br />The abnormal phenomenon, filmed at Huzhong Nature Reserve and provided by local media with permission on Monday (May 15), shows the more than one-metre-high ice blocks on a river, while photographers examine them.<br /><br />Since the altitude of Huzhong District is high, the ice will not completely melt until June every year.
