According to the Mountain-climbing Management Center of the Sport Administration of Tibet Autonomous Region, 300 mountain-climbing amateurs have arrived at Tibet in a bid to conquer various mountain peaks in Tibet，including the Qomolangma (also known as the Everest in the West).

Zhang Xingming, director of the Mountain Climbing Management Center said that mountain-climbing this year lasts from early April to early June. By April 17, altogether 327 mountaineers from nearly 20 countries and regions including Russia, the US, Britain, Swiss and Italy have already come to Tibet, half of whom will challenge the Qomolangma peak, known as the "world rooftop". The rest will march toward other mountain peaks of the Himalaya Mountains such as the Qowowuyag peak, the Xixabangba Peak and the east peak.

Meanwhile, another mountain-climbing group consists of 21 experienced mountaineers from within China has also arrived in Tibet with the aim for the "world rooftop".

Zhang added that in order to guarantee the safety of mountaineers, China has dispatched 50 staff members to the mountainous areas to provide service needed while monitoring safety regulations and the environment. In a few days, leaders of the Mountain-climbing Management Center will also go to the mountains to inspecte service provided and safety measures.

The mountain-climbing activity, in the Himalaya Mountains, in particular, is operated seasonally due to weather conditions. Mountaineers are apt to suffer from injuries in cold and terrible climate in winter; whereas in summer when ice thwarts with the rise in temperature and there is penty of precipitation, the visibility is limited and the avalanche is likely to occur. So mountain-climbing is usually held in spring or autumn，Zhang added.
