Who is that unmasked man? Facebook founder Mark Zuckerberg shrugs off Beijing’s smog on Tiananmen Square run

Facebook founder Mark Zuckerberg shrugged off the return of the smog to Beijing on Friday morning by not wearing a face mask as he said “hi” to residents while jogging in Tiananmen Square.
It’s great to be back in Beijing! I kicked off my visit with a run through Tiananmen Square, past the Forbidden City and over to the Temple of Heaven
Although Facebook is still blocked in China, it did not stop the technology guru from posting his picture while out running in the capital.
“It’s great to be back in Beijing! I kicked off my visit with a run through Tiananmen Square, past the Forbidden City and over to the Temple of Heaven,” Zuckerberg wrote in his Facebook post.
He is in Beijing to attend Saturday’s start of the three-day China Development Forum, sponsored by the Development Research Centre of the State Council.
Zuckerberg will take part in a discussion alongside Alibaba chairman Jack Ma.
In his Facebook post, Zuckerberg said the run had marked him reaching a distance of 100 miles (160km) in his “a year of running” plan after setting himself a target to run 365 miles this year.
The photograph linked to the post shows Zuckerberg running with five other people – all of them without a face mask.
