Adili Wuxor also believes his achievement was set at the highest elevation.
The Guinness World Records headquarters in London has denied Adili Wuxor is one of their world record holders.
Adili, from Xinjiang, has just spent 60 continuous days living atop Bird's Nest during which he spent a total of 198 hours and 38 minutes walking on a thin steel wire above the national stadium.
While news spread across the country that Adili had become a new Jinisi record holder, many took it for granted that it was the original institution in England. But a spokesman for Guinness World Records confirmed that they have had no contact with Wuxor nor have they adjudicated or presented a record to him previously.
The spokesman said the current Guinness World Record for tightrope endurance is 205 days, lasting from Jan 1 - July 25,1993, set by Jorge Ojeda-Guzman of Orlando, Florida, USA, on a wire 11 m long, which was 10.7 m above the ground..
Yang Cheng, manager of the national stadium Co Ltd, later confirmed that what Adili achieved through this event was a Shanghai Big World Jinisi Records, or "China Records" as the company's official website describes them.
The company presented Adili a certificate on July 2 after the Beijing notary office validated the whole process with two clerks observing the event 24 hours a day, Yang said.
The Jinisi Records and Guinness Records have nothing in common, except that they have exactly the same pronunciation when said in Chinese, which was the source of people's confusion.
But that seemed to make no difference in the eyes of Adili. Though Guinness Records are more recognizable world wide, Adili seemed to be happy with the domestic one.
"I think the Shanghai one is more strict and careful in the validation process which alone cost us a total of 30,000 yuan," he said.
Adili said the reason he didn't apply for a World Guinness Record was that he believed people should trust more in their own things, adding that he was disgusted with those who always looked down on domestic honors.
"China has a much larger population than Britain does," he said. "Of course, we should believe China records are more persuasive."
He also believed his record was set at the highest elevation.
