The climber was well known on Chinese social media sites, such as Huoshan and Kuaishou, for his videos which showed him dangling from skyscrapers without safety equipment.
After days went by without Wu Yongning posting videos, his followers became concerned.
His girlfriend and authorities have only recently confirmed his death.
Chinese media reported that he was participating in a challenge to win a substantial amount of prize money.
Wu Yongning, 26, fell from the summit of the Huayuan Hua Centre in Changsha as he attempted to win £11,200 for a competition.
His girlfriend wrote online last week: “Today is December 8th. It makes me think of November 8th, the day you left us and left this world.”

The Changsha Evening News said the 26 year old was trying to make money for his family and pay medical costs for his mother, who suffers from a mental condition.
The South Chine Morning Post quoted the former movie stunt-man’s step-uncle as saying he was “planning to propose to his girlfriend [the day after the challenge].”
“He needed the money for the wedding, and for medical treatment for his ailing mother.”
The social media star filmed the stunt as he shared all of his challenges on Weibo.
But the shocking clip has now emerged, showing him attempting several pull-ups before losing his grip and plunging to his death.
He had previously been referred to as the “Chinese Superman” and was thought of as a ‘pioneer’ of ‘rooftopping’ in his country.
