"It's not been easy for me to reach the peak of Mount Everest which I've dreamed of".
What makes Xia's journey to the Everest more interesting is the fact that his legs were amputated below his knees after he suffered a frostbite while climbing the mountain forty-four years ago.
Xia first attempted to scale Mt Everest with a Chinese government-backed team in 1975 at the age of 25, but was thwarted by bad weather.
But at the start of the year, it appeared the moment would never come for Xia. But, Xia received permission in March this year when the government overturned the decision by calling it "discriminatory" toward people with disabilities.
Now aged 69, he became the second double amputee to scale Everest - and the first ever from the Nepalese side. It also represents a personal challenge, a challenge of fate, ' Mr Boyu told AFP before heading to the mountain. Over the next few days, scores of climbers will head to the top of the 29,029-foot peak.
Steve Plain also took advantage of the first day possible to reach the summit, setting his four-month speed record for the seven continents.
In 2006, Mark Joseph Inglis of New Zealand became the first double-leg amputee to climb Everest from the Chinese side, summiting the peak after 40 days of climbing. Another climb the following year was aborted after the Nepal natural disaster.More news: Fox, ABC and NBC Cancel More Shows

Xia announced on Weibo, China's equivalent of Twitter, that he had successfully scaled the mountain on Monday. Xia, his fellow team members and the Sherpas supporting them summited the mountain early in the morning, according to Imagine Trek and Expedition, the group leading the effort.
During his attempt on the mountain in 2016 he got within 94 metres of the summit, but there was a sudden snowstorm.
He beat the previous speed record by nine days and was presented with an award at the peak. He began January 16 with Mount Vinson in Antarctica, followed by Mount Aconcagua in South America, Mount Kilimanjaro in Africa, Mount Carstensz Pyramid in Papua New Guinea, which covers Australia and Oceania, Mount Elbrus in Europe and Denali in North America. I have to realise it.
Plain, 36, who broke his neck in a bodysurfing accident almost four years ago, climbed the 4,892m Vinson on 16 January.
Climbers try to minimise the time they spend in the aptly named "Death Zone" - an area above 8,000 metres on Everest where there is less than a third of the oxygen found at sea level.
Xia and Plain are among 500 climbers from 38 teams attempting to reach the summit this season.
