A 24-year-old Chinese advertising agency employee has reportedly died from working too much.
In the month before he died, Li Yuan worked overtime until 11pm each day at the Ogilvy & Mather China offices in Beijing, Yangzi Evening News reported.
Li reportedly cried out and suddenly fell to the ground while at work at 5pm on Monday local time.
Colleagues called emergency services and he was rushed to hospital, but eventually died.
Doctors said he had suffered a heart attack, a co-worker said.
Social media users and Chinese weblog Shanghaiist have attributed Li's unexpected death to work exhaustion.
Nearly 600,000 employees die from work exhaustion in China every year according to a report in the China Youth Daily.
These deaths are normally caused by stress which leads to a heart attack or stroke, Want China Times reports.
Ogilvy China confirmed one of its employees had died on its Twitter account yesterday.
"Unfortunately the sad news is true," the company tweeted.
"Beijing has lost 1 of our own.
"He was loved by all of us.
"Thank u for your kind msgs."
