Beijing expected to enjoy return of blue sky by Sunday

Residents in Beijing are expected to see the lingering smog begin to disappear on Saturday and be able breathe clean air on Sunday, offering relief from the polluted air that has engulfed the capital since Dec 30.

Other smog-engulfed provinces like Hebei, Henan and Shandong will see improvements on Sunday when winds come from the north, the Ministry of Environmental Protection said.

In addition to the smog, the capital has experienced more hazy days.
