According to Nepal's tourism department, the official government body which issues climbing permits for the Qomolangma expedition, 346 mountaineers from Nepali and foreign teams have taken the permits for expedition this year.
Lakpa Sherpa, 44, the world's most successful female Everest climber, also made her ninth climb to the top of the mountain on Wednesday - breaking her own record set a year ago.
Kami Rita Sherpa, 48, stepped atop the peak of the 8,848-meter mountain, the world's highest, at 8.30 a.m., beating the record he shared with fellow guides Apa Sherpa and Phurba Tashi Sherpa, who have both climbed the mountain 21 times and do not have plans to climb it again.
The US-based Lhakpa has repeatedly broken her own record for the most Everest summits by a woman. A group of Nepalese sherpa guides reached the summit of Mount Everest, fixing ropes and clearing paths for other climbers to begin their ascent to the peak.
Sherpa climbed the Everest for the 21st time in 2017.
The first summit wave happened Monday when some 50 mountaineers and Sherpa guides scaled it.
He completed the seven climbs in 177 days - nine days quicker than the previous record - after reaching the top of Everest on Monday (May 14).
Mountaineering has been his family tradition.
Mr Kami Rita first reached the top of Everest in 1994 when working for a commercial expedition. In the autumn, he guides clients to smaller peaks in Nepal.
Before leaving for the mountain last month, he told the Associated Press he wanted to scale Everest at least 25 times.
"This has paved the way for other climbers to reach the summit as well".
The route to the summit was opened up by a team of Sherpas earlier this week. She was making her way down to the advanced base camp, he said.
