That's how it went Thursday in much of north and east China, as a heat wave persisted with temperatures of more than 40 C (129.6 F) in many areas. And according to the Central Meteorological Center, the scorching weather will not end until cold air sweeps from north to south Sunday.

Beijing witnessed three hot days in a row from Monday to Wednesday, with the mercury soaring to 37 C (124.2 F) across the city and as high as 40 C (129.6 F) in some areas, the Beijing Meteorological Center said.
The Beijing Meteorological Bureau upgraded its temperature warning to orange alert Wednesday, which meant the temperature had exceeded 37 C (124.2 F)for two days after it issued a yellow alert.
